The Lilac Beauty is a member of the "Thorn" sub-family and is a woodland and hedgerow species that I occasionally catch in the garden. It has been a once a year moth until this year when I've had two so far. All the records here have been in the first half of July.

It is an unusual member of the Lepidoptera. Normally we are used to seeing moths and butterflies with their wings flat, whether they have them open or closed, but this species holds them in a different way.
The wings are folded from the front edge making then look like a crumpled leaf. The other species of this group do hold their wings at various angles when at rest, but this is the only one that actually folds the wings in this fashion.
