Hawthorn Sawfly

Arge melanochra

Description

Body length 7 - 8mm. Much like A. cyanocrocea, the head, antennae and thorax are black and so is the tip of the abdomen, but the fore-wings are clear with a black spot mid way and an orange leading edge.

Habitat

Woodland edge, hedgerows where the adults feed on the pollen and nectar of umbellifers such as Hogweed and the larvae feed on Hawthorn leaves.

Status and distribution

Local and restricted to the south-east of Britain. Uncommon in Nottinghamshire and recorded once at Netherfield Lagoons.

Best time to see
