Dear Readers, I am always happy to see a plume moth, especially as the last one that ventured in was squashed by my cat – I only wish she had such success with the clothes moths. You might be more familiar with the Hemp-Agrimony Plume moth (Adaina microdactyla) or maybe that’s just me, what with having the plant in the garden. I always find these sitting on the front door.
The wings are unusually constructed, as you can see – at rest the wings are rolled up like a Venetian blind. Plume moths are closely related to the many-plumed moths, which take the wing construction to a whole new level – (Alucita hexadactyla) has wings that look like feathers.
Although these wings probably aren’t ideal for flight, they do seem to be useful for camouflage – both the beautiful plumed moth and the hemp-agrimony plume moth look like pieces of dead grass when they are in their natural habitat. Alas, they are rather more noticeable against a plain wall, as my cat will attest.
The beautiful plumed moth on my kitchen wall is probably looking for a place to hibernate, as the adult moths spend the winter dozing away, before heading off in spring to mate and lay its eggs. The larvae have wide and varied tastes, and will munch on mints, thistles, heathers and geraniums, but rarely reach pest status in this country. Besides, my water mint has gone berserk this year, so if these little critters will keep it all in check I will be only too happy.
