Scalloped Oak (Crocallis elinguaria)
The Scalloped Oak is a common moth and frequently turns up in the moth trap as it is particularly attracted to light.
It is single brooded and flies in July and August. It frequents a wide variety of habitat but likes to lay its eggs on deciduous trees and shrubs, but not exclusively oak as the name might suggest.
It overwinters as an egg and hatched into a larvae in April before emerging as this adult in July.
