Light emerald moth, Campaea margaritata

2nd September 2006, Saturday

While walking the other day, a light emerald moth flew past and landed in the grass nearby. They seem to be quite a restless species, often about in daytime. Why, I wondered, are they such an obvious colour when most of their bretheren are so cryptic. Some lichens, I suppose, do approach this rather aniline colour, but the moth, so far as I know, makes no attempt to find such refuges. Maybe it is a ‘keep away’ signal, but red or yellow usually mean ‘stop’ rather than a curious sea geen. Perhaps they hide away under silvery green leaves.
Whatever the reason, it is common enough, so it must be a ‘safe’ colour.
