Marbled Green & Marbled Beauty

Marbled Green and Marbled Beauty are both moths whose larvae eat lichens. I catch the former quite frequently during their flight period in the summer, as they are common on house walls. Marbled Green is a new species for the garden, but it also can be found on limestone dry-stone and house walls with lichens. This one took me a while to identify as is it not the typical green colour usually seen.
