The Latest on Sunrise and Pudding

Dear Readers, it’s fair to say that my foster kitties, Sunrise and Pudding, are really starting to relax and come out of their shells now. You might remember that the black cat, Pudding, hid behind the books on the bookshelf when we first started looking after her, so all you could see were two ears and two terrified eyes. But this is a pretty quiet household, and both cats have gradually taken over the place.

Every evening before bed time Pudding comes up onto the sofa with me and  rolls around like a lunatic.

But mostly they sleep, often cuddled up together on the very convenient IKEA chair…

Though a few weeks ago we moved the bird table, and now the cats spend a lot of time squirrel watching…

You might also remember that the cats have a touch of food anxiety (i.e. they wrestled a loaf of bread to the ground  and ate the crust on one occasion). We’re now giving them four small meals a day, but I also decided to hide a tiny bit of dry food in an egg box to give them a bit of a challenge. Well, suffice to say that that was a ten-minute wonder.

I shall have to invest in a ‘proper’ puzzle feeder, I fear. I am also wondering about a cat tree that’s tall enough that they can look out of the window (we have privacy film on the lower part of the living room window) but clearly it needs to be robust enough not to fall over, and not too hideous to look at.

But honestly, you’d think someone would have adopted these two by now. They are absolutely adorable, and not at all a nuisance once they settle down and relax. If you live in London and think they might work for you, you can contact the RSPCA on the link below….

Thursday Poem – The Darkling Thrush

Dear Readers, Thomas Hardy is rather out of fashion these days, but in mitigation I’d like to offer this, which I think captures the moment when a song thrush sings on a winter day better than anything I’ve ever read. And it’s hopeful, and goodness knows we could all do with a bit of that.

The Darkling Thrush

By Thomas Hardy

I leant upon a coppice gate
When Frost was spectre-grey,
And Winter’s dregs made desolate
The weakening eye of day.
The tangled bine-stems scored the sky
Like strings of broken lyres,
And all mankind that haunted nigh
Had sought their household fires.

The land’s sharp features seemed to be
The Century’s corpse outleant,
His crypt the cloudy canopy,
The wind his death-lament.
The ancient pulse of germ and birth
Was shrunken hard and dry,
And every spirit upon earth
Seemed fervourless as I.

At once a voice arose among
The bleak twigs overhead
In a full-hearted evensong
Of joy illimited;
An aged thrush, frail, gaunt, and small,
In blast-beruffled plume,
Had chosen thus to fling his soul
Upon the growing gloom.

So little cause for carolings
Of such ecstatic sound
Was written on terrestrial things
Afar or nigh around,
That I could think there trembled through
His happy good-night air
Some blessed Hope, whereof he knew
And I was unaware.

Wednesday Weed – Hazel Revisited Again

Dear Readers, I’ve written about hazel a couple of times before (see below), and so today I wandered out into the garden to see if there were any catkins on the hazel in my hedge. Not a single one! And yet for me, these ‘lambs tails’ shivering in an icy breeze are a sign that spring can’t be far away. I have no idea why I don’t have catkins as the hedge hasn’t been trimmed for ages – maybe like a ‘mast’ year with other trees, it only flowers when it feels the conditions are right. Are you spotting hazel catkins yet in your part of the world?

And for the fungi lovers amongst us, I note that hazel is the sole host for the Rubber Glove Fungus (Hypocreopsis rhododendri) in the UK, where it grows on the west coast of Scotland and Ireland. Interestingly, it’s also found in the Appalachian Mountains of the US, where it grows exclusively on native rhododendrons, hence the scientific name.

And now for a poem, and a bit more on the hazel.

Dear Readers, when I was writing my garden update yesterday, I suddenly wondered if I had ever done a ‘Wednesday Weed’ on hazel, and indeed I had, back in 2015. I remember wandering the streets of East Finchley on a cold and blustery day, and wondering what on earth I was going to write about, when suddenly I noticed the catkins outside Martin School. Writing this blog has really reminded me to pay attention, even on the most unpromising of days.

We are just coming up to the busiest time of the year at work, when it feels like nothing but deadlines, but I am reminded that nature is going on all around us all the time. And because I love it, here is my favourite hazel poem. I always wondered what an Aengus was, but according to the interwebs, Aengus was the god of love in Irish mythology. Yeats himself described the poem as “the kind of poem I like best myself—a ballad that gradually lifts … from circumstantial to purely lyrical writing.”

The Song of Wandering Aengus
BY WILLIAM BUTLER YEATS

I went out to the hazel wood,
Because a fire was in my head,
And cut and peeled a hazel wand,
And hooked a berry to a thread;
And when white moths were on the wing,
And moth-like stars were flickering out,
I dropped the berry in a stream
And caught a little silver trout.

When I had laid it on the floor
I went to blow the fire a-flame,
But something rustled on the floor,
And someone called me by my name:
It had become a glimmering girl
With apple blossom in her hair
Who called me by my name and ran
And faded through the brightening air.

Though I am old with wandering
Through hollow lands and hilly lands,
I will find out where she has gone,
And kiss her lips and take her hands;
And walk among long dappled grass,
And pluck till time and times are done,
The silver apples of the moon,
The golden apples of the sun.

And now, let’s zip back to 2015 and see what I had to say about hazel back then.

Hazel Catkins (Corylus avellana)

Hazel Catkins (Corylus avellana)

Dear Readers, this week the search for a Wednesday Weed sent me in a completely different direction from my usual route. On a rainy, blustery day, I headed off towards our local primary school, to see if the playing fields there had anything growing that I had not already covered. In vain I peered through the fence at the turf, until my eyes refocused and I realised that I’d been looking at my subject all along. For what is more surprising on a January day than a plant that is already in full flower, ready to reproduce when everything else is still in bed?

Male Hazel Catkin

Male Hazel Catkin

The male Hazel catkin has the delightful colour of a sherbet-lemon. With every damp gust, invisible clouds of pollen are released. With any luck, they will be captured on by the red female flowers  who wait with open arms, a little like sea anemones.

Female Hazel Catkin

Female Hazel Catkin

It is these female flowers that will eventually turn into hazelnuts. They will promptly be nibbled off by squirrels or, if we are extremely lucky, by dormice. Kentish Cobnuts, with their creamy white interiors and little hats of pale green, are a domesticated variety of the hazelnut, but the wild variety is perfectly good to eat, and was, indeed, one of the staple foods of prehistoric peoples. Hazel has grown in the UK for at least the last 6000 years, and only birch was quicker to colonise the country after the last Ice Age. The spread of the plant throughout Europe has been attributed to its being carried from place to place by humans. After all, nuts are a concentrated, portable form of protein and carbohydrate. What better food if you’re embarking on a (very) long walk?

The Hazel growing beside the school playing fields has turned itself into a small tree, but historically it is much coppiced, the stems being used for a wide variety of purposes. They are extremely flexible, and can be turned back upon themselves or knotted. They were woven together to form both hurdles and fences, and were also used as the framework for wattle and daub walls. They are still used in thatching, to hold the thatch down, because the hazel stems can be bent through 180 degrees. A more modern use is in the creation of sound screens alongside motorways.

A plant which has lived alongside us in these islands since the very beginning, Hazel has many associations with Druid and Celtic beliefs. Its stems have been used for water divination, and for the making of shepherds’ crooks and pilgrims’ staffs. A Hazel tree was believed to be the home of Bile Ratha, the poetic fairy of Irish folklore, and it was believed that eating hazelnuts would bestow wisdom. On Dartmoor, Hazel was said to be the cure for snake and dog bites. And, to prevent toothache, you simply have to carry a double-hazelnut in your pocket at all times.

IMG_1044The catkins are shivering in the wintry blast, and so am I. Parents are tearing past me in their cars, hurrying to pick their children up from the school gate and giving me a decidedly funny look as I stand in the rain, peering through the fence with my camera.  I wonder if any of the children will get the chance to admire the catkins, the first sign that the long dark is finally loosening its grip. I hope that someone will take the time to show the little ones the ‘lambs tails’, and explain to them about this plant. After all, we have been living together, side by side, for six thousand years.

Nature’s Calendar – 5th to 9th January – The Light Steals Back

The Adoration of the Magi – Edward Burne-Jones (1894)

Dear Readers, a few years ago I was following the 72 seasons of the British year, as described in the wonderful book ‘Nature’s Calendar‘. so I thought I might have a bash at doing the same thing this year. Let’s see how we get on! It’s interesting to see how the book ties up with what I’m actually observing, and for the period 5th to 9th January the authors look at how the light is gradually, gently coming back.

However, the mornings seem every bit as dark as ever, even though sunset does seem a tad later every day. I’ve always found this very hard to get my head around. In her piece in the book, Lulah Ellender explains that this is because of the difference between Solar time and Clock time. Solar time is measured according to the Earth’s position relative to the sun, which is affected by the tilt of the axis, the fact that our orbit isn’t circular, and by the speed that the sun itself travels. Clock time takes a measurement of where the Earth would be in relation to the sun without these disparities. A Clock-time day is 24 hours long, and noon and midnight fall at set times. A Solar-time day runs from the highest point of the sun one day, to the highest point of the sun on the next day. In the northern hemisphere, the Earth tilts closest to the sun and is spinning faster than clock time. So, until 9th January our sunrises stay static – after this, we should notice a bit more light at both ends of the day.

Go figure! My head explodes with stuff like this. So much of what we live by is arbitrary – the date of New Year, the time when the sunrises and sets. I am reminded that not too long  ago, the UK had ‘local time’: for example. Bristol time was 11 minutes behind London time, and in Truro the time was 20 minutes later than here in good old East Finchley. In 1840 Greenwich Mean Time was adopted, mainly because the burgeoning railways demanded a standardised time across the country, but a study showed that actually some areas were very slow to adopt this, and there was something of a free-for-all until 1880. I imagine that only the rich had watches, and everybody else relied on the town hall clock.

Another thing that pops up in Ellender’s chapter in the book is that this very day (6th January) is Epiphany – for Christians, the day when the Three Wise Men finally reached Bethlehem. 7th January is Distaff Day, traditionally the day when women would get back to spinning and weaving after the Christmas break, while the first Monday after Epiphany is Plough Monday, when the chaps get back to the fields. There was often much jollity around these two days: on Distaff Day, the men would try to set fire to the womens’ distaffs (the rod where the wool or flax was kept) before the women could douse the distaffs (and hopefully also the men) with buckets of cold water. I imagine this was a whole lot of fun on a cold January evening.

Reine Berthe et les fileueses, 1888 by Albert Anker – Queen Bertha shows the young women of the court how to spin.

Those of you who studied English might also remember that James Joyce thought of the epiphany as a moment of revelation, one of those times when something quite ordinary somehow seems to be lit up with an inner light. This is the piece that I remember most: the bird-girl from A Portrait of the Artist as a Young Man. Looking at it today it has resonances about the male gaze etc etc, but I still think it’s an extraordinary piece. See what you think.

A girl stood before him in midstream, alone and still, gazing out to sea. She seemed like one whom magic had changed into the likeness of a strange and beautiful seabird. Her long slender bare legs were delicate as a crane’s and pure save where an emerald trail of seaweed had fashioned itself as a sign upon the flesh. Her thighs, fuller and softhued as ivory, were bared almost to the hips, where the white fringes of her drawers were like feathering of soft white down. Her slateblue skirts were kilted boldly about her waist and dovetailed behind her. Her bosom was as a bird’s, soft and slight, slight and soft as the breast of some darkplumaged dove. But her long fair hair was girlish: and girlish, and touched with the wonder of mortal beauty, her face.

She was alone and still, gazing out to sea; and when she felt his presence and the worship of his eyes her eyes turned to him in quiet sufferance of his gaze, without shame or wantonness. Long, long she suffered his gaze and then quietly withdrew her eyes from his and bent them towards the stream, gently stirring the water with her foot hither and thither. The first faint noise of gently moving water broke the silence, low and faint and whispering, faint as the bells of sleep; hither and thither, hither and thither; and a faint flame trembled on her cheek.

—Heavenly God! cried Stephen’s soul, in an outburst of profane joy.

He turned away from her suddenly and set off across the strand. His cheeks were aflame; his body was aglow; his limbs were trembling. On and on and on and on he strode, far out over the sands, singing wildly to the sea, crying to greet the advent of the life that had cried to him.

And happy Epiphany! Make sure you lock up your distaffs for 7th January  too. You never know when someone will appear with a bucket of cold water.

The Twelfth Day of Christmas – Winter Bumblebees

Bumblebee on Winter Honeysuckle

Dear Readers, there has been a lot of news about flowers blooming out of season this week, to coincide with the Botanical Society of Britain and Ireland’s (BSBI) annual Plant Hunt. Over the years, this citizen science project has recorded a change in when plants flower, with many plants blooming earlier than they used to. There was a very interesting NHBS talk about this very subject during lockdown (I reported on it here).

One result of the milder winters is that some bumblebee colonies are surviving right through the winter, instead of dying off. A more common sight, however, is a queen bumblebee popping out on a mildish day for some nectar. My very first post was on this subject, and it’s one of the main reasons that I try to make sure that I have something in flower all through the year, just in case. Winter Honeysuckle is a great favourite, as is Mahonia, and that so-called ‘thug’ Green Alkanet is also often around.

Bee on Fatsia japonica in central London in late November

Some exotics that may still be in flower in sheltered spots include Fatsia japonica, a real bumblebee magnet, some Hebes, and some clematis, all of which can provide food for queen bumbles on a mild day. The bumblebee in the photo below was snapped on my birthday in January.

So, while the world is definitely out of joint, with flowers blooming and bees emerging at times when you would not normally see them, there is a little bit that we can do to help our fellow creatures – plant some late/early flowering shrubs or bulbs, and see who turns up! Though good luck if you’re planting crocuses, because they are a great favourite with some of our other furry friends…

Crocus bulbs after the squirrels had had a nibble….

And that’s the end of the Twelve Days of Christmas! The decorations are stowed away for another year, the diary is full of Open University assignments (and rather too many visits to the theatre to be compatible with the assignments, but hey), the days are gradually getting longer and once it gets above freezing I will be out and about again. I hope the season has been/is being kind to you and yours, and here’s to another year of nature!

The Eleventh Day of Christmas – The Christmas Spider

Christmas Spider ornament (Photo By Erika Smith – MSI Chicago – Christmas Around the World 2007 – Ukraine – spider web ornament, CC BY-SA 3.0, https://commons.wikimedia.org/w/index.php?curid=37156527)

Dear Readers, the legend of the Christmas Spider is thought to come originally from Western Ukraine, and it goes like this.

Once upon a time, a poor but hardworking widow lived in a hut in the forest with her children. One  day, a pine cone fell through the roof (as they do) and a fir tree started to grow in the middle of the hut. The children and the widow watered the tree, and were delighted to see the tree thrive  but, as Christmas approached, they were sad because they had no money to buy decorations. When they awoke on Christmas morning, spiders had spun their webs all over the tree, and when the sunlight touched them, they were turned into silver and gold. Which was handy for the little family, who never suffered poverty again.

The End.

Some people believe that this story is the reason that we pop tinsel onto our trees, and other countries also claim the legend and make it their own – in some versions its Santa Claus or the Baby Jesus who are responsible for the transmutation of the  webs into precious metals, and some versions are told from the perspective of the spider, though if I had all my hard work turned into something utterly useless to me (whoever caught a fly on a gold thread?) I think I’d be mightily fed up.

In Ukraine, little spider ornaments called pavuchky are placed on Christmas trees to bring luck.

 

The blog that this photo comes from is a lot of fun – the author is finding different  national traditions to incorporate into their lives. Well worth a look! Although it seems to have finished a few years ago. It’s always  sad when a blog suddenly ceases to exist. I used to avidly follow a literature blog called ‘The Dove Grey Reader’ a few years ago, and was bereft when that finished.Incidentally, good old Australia has, in addition to Christmas Beetles, an actual Christmas Spider – this is related to our common garden orb-weaver, but is rather more brightly coloured, and very varied.

These are smallish spiders (growing to a maximum of 12mm long) but they are gregarious, and can build an aggregation of overlapping webs, which can be a bit of a pain if you’re trying to walk along a path and encounter the robust threads at head height. Australia does seem to be especially blessed in interesting invertebrates (and other animals) and is the only place where you’re going to find the Christmas Spider. I must make a visit one day!

The Tenth Day of Christmas – The Wasp King

Photo by By David Lienhard – Imported from 500px (archived version) by the Archive Team. (detail page), CC BY-SA 3.0, https://commons.wikimedia.org/w/index.php?curid=71295801

Dear Readers, gather round while I share a most delightful Christmas story, thought to have originated in the 1600s, and to still be heard in Scandinavia, eastern Europe and, apparently, the Yorkshire Wold.

Once upon a time, a farmer did a deal with the devil on Christmas Eve – his only son would become a lawyer, and the farmer would give the devil everything that he possessed, including his soul. The son soon achieved his father’s ambition (in spite of not being the sharpest knife in the drawer), so the devil came back the following year for his payment. What could the farmer do? He suggested to the devil that, before he handed everything over, the devil could taste some of the most wonderful honey in the world if he would only reach into this suspiciously buzzy hole in the ground. Well, clearly the devil wasn’t as clever as he’s cracked up to be, because greediness got the better of commonsense. The devil put his hand into the hole in the ground, and was promptly stung vigorously by no less than the King of the Wasps.

Brief biological correction – male wasps don’t have stings, so this is clearly a fabrication. On you go.

Well, the devil ran off howling, and the farmer was feeling very pleased with himself until the wasp gave him what was known as an ‘old-fashioned look’ in my household. The King of the Wasps was not up for being used in this fashion! And so he stung  the farmer to death.

The End.

Now, apparently the legend of the Christmas wasp was used for a long time to scare the hell out of small children (like a six-legged stripy ‘Elf on the Shelf’ only with a sting and an aggressive manner). And to appease him, striped cakes called Hvepekager or Wasp Cakes were laid out at the Winter Solstice. Sadly, I can’t find a single picture of this baked delight, but apparently it’s made from dark rye and light wheat. I suspect that it isn’t  eaten by the Wasp King, but probably by tired parents, only too keen to persuade their children that they better behave themselves.

Mostly, at this time of year, the only wasps left in the UK are queen wasps, slumbering away in an attic or shed or garage, bless them. Such useful insects! They strip caterpillars from our cabbages, and have even been seen carrying away ant larvae to feed their young. Let’s just make sure that we don’t take advantage of their good nature.

The Ninth Day of Christmas – The Snowflake Bug

Dear Readers, as the cold weather arrives here in the UK (with a chance of snow), I thought I’d draw your attention to this remarkable insect. This particular one is found in Madagascar, where it spends its life in the dry tropical forests. The adults are gregarious, and rely on their resemblance to a pink petal to distract predators, but the nymphs are covered in a waxy white substance that can  make them look a little like a snowflake.

These little guys are very mobile, shuffling about on a plant  stem and even leaping into the air if disturbed. The family that they belong to (the Flatidae as you ask 🙂 ) is very widespread, with variations in Asia and in North and South America.

This is the Madagascan one….I love all the insect and frog sounds in the background too…

https://www.youtube.com/watch?v=zQ9r_cCastA

This one, that looks a little like a cotton bud or piece of popcorn, is from Ecuador…

https://www.youtube.com/watch?v=ip4qpKXPyd4

And here are some from Burma, though calling them ‘Ridiculous’ and ‘Comedy Creatures’ doesn’t give them enough respect in my view.

https://www.youtube.com/watch?v=3EVLJChVV48

What all these bugs have in common is a great love for plant sap – they exude honeydew, and  this makes them popular with some birds, who might either eat the bugs themselves, or drink up the honeydew exuded onto leaves. In Madagascar, the Coquerel’s Coua is a honeydew specialist.

Generally, though, those white waxy excrescences on the back of the bug work not only to make it look like a piece of lichen, but to extend their ‘radius of sensitivity’ – the slightest touch of one of the ‘hairs’ is enough to make it spring into the air, as we see in the Burma clip above. What splendid and unlikely creatures these are!

The Eighth Day of Christmas – Mistletoe Eaters

Mistletoe Marble Moth (Celypha woodiana) Photo from https://butterfly-conservation.org/moths/mistletoe-marble

Firstly, Readers, Happy New Year! May it be a happy and healthy one for all of you lovely people. In view of all the ‘stuff’ going on at the moment, though, it’s tempting to agree with Ogden Nash…

Good Riddance, But Now What?
Come, children, gather round my knee;
Something is about to be.
Tonight’s December thirty-first,
Something is about to burst.
The clock is crouching, dark and small,
Like a time bomb in the hall.
Hark! It’s midnight, children dear.
Duck! Here comes another year.
–Ogden Nash

If nothing else, let’s preserve our sense of humour.

And now, back to the invertebrates of Christmas. It’s hard to imagine any creatures getting much sustenance from mistletoe, but there are six species of insect that depend upon it for their living. First up is the Mistletoe Marble, a tiny moth that looks like a bird-dropping (very handy for camouflage). The caterpillar lives between the layers of the mistletoe leaf, causing a blister gall.

Blister gall on mistletoe – Photo by Dave Shenton at https://butterfly-conservation.org/moths/mistletoe-marble

The Mistletoe Marble is declining, probably because our orchards are disappearing – it is usually found on the mistletoe in old apple trees. It’s been suggested that preserving the species (which has a Biodiversity Action Plan (BAP) in place) might mean drinking more cider. Alas, a superfluity of the stuff when I was a student has left me unable to stomach the stuff, so you lovely people will have to drink my share.  Cheers!

Then there’s the Mistletoe Weevil (Ixapion variegatum). The eggs of this little beetle (much smaller than some of its relatives so you could say it’s the lesser of (at least) two weevils) are laid on the stems of the mistletoe, and the larva buries into the stem, causing it to become distorted. When it hatches, the adult weevil feeds on the leaves of the mistletoe, causing brown speckling. I’ve just discovered the blog The Mistletoe Diary, a great source of information re all things mistletoe-related. There is a theory that the Mistletoe Weevil only targets stressed mistletoe,  but the author of the blog suggests that maybe it’s the other way round – it’s the weevil that’s stressing the mistletoe by burrowing into it. Nothing in nature is ever straightforward.

Incidentally, I rather like the alternate name ‘Kiss-Me-Slow Weevil’. Ostensibly it’s named because of the mistletoe collection, but we don’t give our insect friends enough love in my opinion, so if you see one, give it a quick peck so that it knows it’s appreciated.

And finally, there are four species of true bug which feed on mistletoe. Some of these are relatively new to the UK, but as they’re all so small they could easily have been hiding in plain view. One is the Mistletoe Jumping Louse (Cacopsylla visci), one is a rather pretty plant bug resembling a tiny shield bug (Pinalitus viscicola) and one, which was first recorded in 2003, is a rotund and mottled little chap/pess. All three feed only on mistletoe by sucking the sap.

Pinalitus viscicola (Photo by Tristan Bantock at https://www.britishbugs.org.uk/heteroptera/Miridae/pinalitus_viscicola.html)

Mistletoe Jumping Bug (Cacopsylla visci) Photo Joe Botting at https://www.britishbugs.org.uk/homoptera/Psylloidea/Psylla_visci.html

The fourth bug, though, doesn’t feed on mistletoe directly – it’s a predator, feeding on the plant-eating bugs, particularly the Mistletoe Jumping Bug. Anthocoris visci is a little tiger of the mistletoe, prowling amongst the leaves for herbivores to puncture.

Anthocoris visci – Photo by Timon Boumon at https://observations.be/species/25221/

So, mistletoe is the sole foodplant for a rare moth, an unusual weevil, three bugs which suck its sap and a bug that eats the other bugs. In other words, there’s a whole mini-ecosystem around this hemi-parasitic plant, which normally only gets thought about at Christmas. It’s well worth having a look at any that you have in the house to see if it is home to any insect ‘friends’. 

The Seventh Day of Christmas – The Antarctic Midge

The Antarctic Midge (Belgica antarctica)

Dear Readers, if I was to ask you to guess the largest purely terrestrial organism native to Antarctica you might, like me, scratch your head a bit. Seals aren’t purely terrestrial and neither are penguins. But I would never have guessed that the answer would be a 6mm long midge, named ‘Belgica’  after a Belgian expedition from 1899. The naturalist onboard collected a specimen of this midge, unknown to science previously. But how on earth does it survive in such a cold and barren place?

First up, this midge is flightless – the winds in Antarctica are legendary, and you wouldn’t want to be a tiny insect blown into the water or onto some even more hostile plain. In fact, the Antarctic Midge can only survive temperatures of -15 degrees Celsius, while the Antarctic regularly drops to -40 degrees. Rather the face the extremes of the weather, the midge burrows under the snow, where the temperature rarely drops below a ‘mere’ -7 degrees.

Even at these temperatures, though, the Antarctic Midge requires a bit of antifreeze – its tissues contain glucose, trehalose and erythritol, all forms of sugar that prevent ice crystals from forming, and help to stabilise the proteins and fats that the insect needs to metabolise.

In fact, the Antarctic Midge is so well adapted to freezing temperatures that exposing the larvae to temperatures as low as 10 degrees Celsius will kill them within a week. However, they can survive losing up to 70 percent of their bodily fluids – larvae born on the west coast of Antarctica live without water for the whole of their larval cycle. They reduce water loss by clustering together, and by doubling the concentration of sugars in their bodies, which helps to thicken their ‘blood’ and makes it more difficult to lose fluids.

For such a little creature, the Antarctic Midge has a long life cycle – it can take four years from egg to adult, with two long, cold Antarctic winters spent as a larva, dormant under the snow. During the larval stage, the young midges will eat moss, detritus, fungi and micro-organisms. The timing of the final emergence as adults is crucial – the adult midges will only live for ten days, so they have to find a mate and lay their eggs in this short time. The males emerge first and perform a mating ‘dance’ (similar to that of the Winter Gnats that we heard about a few days ago). The males can mate multiple times, but the females lay only one batch of eggs, after which their reproductive tracts are damaged and they are unable to produce any more. The females cover their eggs in a blanket of jelly which acts both to protect them from freezing and keeps them from dehydrating – this will also provide the first meal for the larvae when they hatch.

I wondered what on earth the female midges fed on, and the answer is ‘nothing at all’ – neither sex feeds after it emerges as an adult. What would they feed on, after all? The penguins are largely not around in the summer, and any animal that they fed on would only have to jump into the water to get rid of their irritating little friend.  The Antarctic Midge is  decidedly preferable (from a human point of view) to the fearsome Scottish Midge, where the females need a blood meal in order to provision their eggs, and they aren’t at all fussy about where they get it (although if I’m in the vicinity they show a distinct preference for me).

What an extraordinary animal the Antarctic Midge is! A survivor and a specialist. Let’s keep our fingers crossed that the Antarctic continues to be cold enough for it to survive, because if it’s too hot for the midge, the consequences for all of us could be pretty dire.
