New Caddisfly - Glyphotaelius pellucidus

Quite a lot of caddis flies are attracted to light, like this one found lurking in a hole in the wall when I was mothing the other evening. This is quite a big and well marked caddisfly, the males and females looking different (this is a male). Glyphotaelius pellucidus is a woodland pond-dwelling species, it’s larvae making a case of dead leaves. It flies in two generations, one in the spring and another in the late summer.
