I've taken many photos of males of this moth courting in groups around Field scabious Knautia arvensis and of females egg-laying in the flower heads, as the larvae feed on this species (and other Scabious). There is even a parasitic wasp that visits flower heads to lay eggs as the moth does, and its larvae then attack the moth larvae… http://www.ispotnature.org/node/452863 The antennae also look the right length for a female Nemophora to me.
