A few moths of 2024

It’s been an odd year so far for us moth-ers. There was an odd burst of numbers and diversity back in mid-March but that was followed by some very lean lighting-ups when it was cold and wet for weeks on end each night. It was only on the 8th May that there was a sudden up-tick. We had warmer evenings and on the night of 12th May, I recorded 36 moths of 25 species. 14 of those were new for the year (NFY) and one of them, Grey Pine Carpet, was new for my garden (NFM).

Next session, wasn’t quite as rich, but there were still seven species NFY, including a couple of Pale Tussock, a Maiden’s Blush, Pebble Hook-tip, The Spectacle, and a White Point. Moth names are just as diverse as the moths themselves.

So, as of 13th May, that’s 84 lighting-up sessions mainly with a 15W Wemlite UV fluorescent tube on a Robinson trap. It’s brought in around 500 moths of 80 species or thereabouts. The next few weeks will see diversity and numbers rising still further.

I’ve written about the industrial evolution of the Peppered Moth on numerous occasions. It’s held up as an example of evolution in action. Here’s the non-melanic, “clean air” form that turned up on the night of 14th May.

The Silver Y is a migrant species turning up in their thousands some years if conditions are right. It is found all over the UK, but seen most commonly, and obviously, at coastal watch points. Its name comes from the silvery Y shaped marking on its wings. The scientific name is Autographa gamma, which suggests that the marking might also be the third letter of the Greek alphabet, gamma. Often to be seen nectaring on wildflowers and garden flowers during the day, at dusk, and at night.

I usually see well over 300 species in the garden over the course of the year and a few dozen of those are NFM (see definition above). I’ve been mothing since late July 2018 and at last count garden “list” stands at well over 500 species.

An update at this point in the year when it seems to be turning seemed timely.
