A Beautiful Golden Y

I caught a Beautiful Golden Y in my trap the other day

A very attractively marked moth

It is a resident and common moth – its caterpillars feed on a variety of herbaceous plants including nettles, ragwort and honeysuckle.

As this picture shows it is closely related to the Silver Y which is an immigrant moth which in some summers can arrive in Britain from the Continent in huge numbers

Dancing Longhorn Moths and a Silver Y

Yesterday I found a little group of Longhorn Moths sitting on and dancing around the leaves of an elm tree.


Look at the length of their antennae! These individuals all appear to be males as their antennae are 3x the length of their wings (in the females they are 1.5x)


I think this species is Adela reaumurella – a common species in England


I also had a single Silver Y in my trap overnight. Not a bad effort for a migrant coming from the south on such a cold night.

A single Silver Y

Most trap was again dominated by Large Yellow Underwings but there was a single Silver Y in the trap. This species is a migrant which breeds in southern Europe and North Africa and then migrates north through Europe to Britain and even as far north as Iceland.

The Latin name for the Silver Y is Autographa gamma – gamma being the Greek letter Y. An autographa is the original parchment that a Biblical manuscript was written on.
