Phlyctaenia coronata. No, I hadn't heard of it either! But there is was in my garden, by the light of the torch, supping away at my Hemp Agrimony flowers.
Fortunately, a gentleman called Jim Porter recently decided to give all the micromoth species found in the UK a vernacular name to complement the Latin name, and so - if you want to - you can now call Phlyctaenia coronata by the rather more accessible name of 'Elder Pearl'.
It turns out that the caterpillars of the Elder Pearl feed on young Elder leaves. I've also found out that an August record is quite late - it is usually seen in June and July. And it also seems to be quite widespread in the country, so if you have Elder growing nearby, this little chap could well be in your flower bed.
It's amazing to think that so many of our smaller creatures have long been known about by the experts. The Elder Pearl, for example, was first classified in 1767 by a man called Hufnagel. And 243 years on, there it is, happily living out its existence in my neighbourhood, and yet I'd never seen it and I expect that no-one else in my street has ever noticed it either.
It's when I see things like this that I wonder what other secrets my garden might hold.

We are trying to build a moth trap to see what is about during the night. Our first attempt was a disaster with no moths at all, a bit of readjustment is called for.
There must be some beautiful moths in our garden, the tricky bit is observing them.
Build it and they will come.
