Idaea aversata: the riband wave

The riband wave (Idaea aversata) is undoubtedly one of the most numerous species that I get in my light trap. It can occur frequently between May and October as it can have multiple broods each year and there are always more than one in the trap when they do occur.

They can be variable in colouring with the central band across the wings becoming almost a solid brown bar in some specimens. I also tend to find many worn and damaged individuals so I guess they are either very fragile or tend to live as adults for longer than some species. That is not a scientific fact, just a personal observation! 

The larvae feed on a wide variety of plants and so the adult moth can be seen almost anywhere in Britain and can sometimes be seen during the day if disturbed from a shrub where it is resting.
