Nemophora metallica

The Brassy Long-Horn is a spectacular micro moth

The Brassy Long-horn Moth is one of the ‘long-horn’ micro moths so named because of their exuberantly long antennae (males only). In Nemophora metallica the male’s antennae are at least three times the length of the forewings.

The moth is a day flying moth of high summer, is restricted to southern England and is Nationally Scarce (B) meaning that it has only been recorded in 31 to 100 ten kilometre squares in Great Britain.

The larvae feed on Filed Scabious (Knautia arvensis), the flower shown in the photo above. The specimen above was found along with many others on Field Scabious growing on the West Kennet Long Barrow, a Neolithic burial mound near Avebury, Wiltshire.
