Dear Readers, the temperature is due to get into the 90’s today, and so I decided it was a good morning to do the Big Butterfly Count for Butterfly Conservation. This year, you can do as many counts as you like, and so I thought I’d maybe do a few between now and the 9th August when it finishes. Sadly the buddleia at the front has pretty much gone over, but the hemp agrimony at the back is still pulling them in. As usual, as soon as I was all set up with my app loaded and my chart at the ready, all the butterflies went on strike. Where were the clouds of holly blues from yesterday? Where were the peacocks and the red admirals? Well, actually I suspected that the big colourful butterflies were all looking for buddleia elsewhere, because in spite of the popularity of my hemp agrimony with all the little butterflies and bees, the big ones don’t seem to like it.
However, there was one moment of great excitement. There was a flash of deep copper-orange, and this amazing moth landed in the lilac.
I love the delta wings (which remind me of my favourite V-bomber, the Vulcan), and the absolute nonchalance with which it flies – presumably the orange colour is a warning to birds that it is unpleasant to eat.
This is actually the second or third Jersey tiger that I’ve seen in the garden during the last few days, and I am wondering if my huge stands of hemp agrimony are actually being used by the caterpillars. How exciting would that be! As the name suggests, the Jersey tiger came originally from the Channel Islands, and the first time I saw one it was in parents’ Dorset garden. A friend saw one in North London earlier this year, and now they seem to be everywhere. The caterpillars can apparently be spotted from September onwards, and the tiny caterpillars overwinter amongst their foodplants, so maybe I won’t cut back my plants this year just in case. They also like all kinds of ‘weeds’, such as nettles, ground ivy and dandelion, so keep an eye open, London folks!
Now, here’s a question for you. When you’re thinking about the weather, do you think in Centigrade or Fahrenheit? All the ‘young’ people in my team at work think it’s hilarious when I tell them that ‘it’s going to be in the 90’s on Monday’ and ask me what the ‘real temperature’ is. Hah! Is it just an age thing? I’m old enough to remember pre-decimalisation (which was in 1971) but I don’t remember ever being told that we had to think in Centigrade. Or maybe it just passed me by. Anyway, it is a constant reminder that I am about 25 years older than the next oldest person in my team (that and not being eager to return to the office because, pandemic).
Anyhow, I also wanted to give you a heads-up about my latest garden experiment. Whenever I go to tropical butterfly houses, I see fermenting bananas left about, and the butterflies seem to love them. So, I have stuck an ageing banana on the bird table (opened of course) and I shall being keep an eye open to see who turns up. I suspect that it might be more attractive to moths because of their well-developed sense of smell, and I’m hoping that wasps are still concentrating on protein rather than sugar at the moment, otherwise things could get very interesting. I shall keep you posted, readers, but in the meantime, keep your fingers crossed for my next butterfly count – let’s hope that I find more than the three large whites and five gatekeepers that I saw this time.
