Abia sericea (Linnaeus, 1767)

Abia sericea

Abia sericea is similar to Abia candens and more common. The antennae in both sexes are usually all yellow and never with segment three bicolorous. In Abia candens the antennae are dark on the apical and basal segments with middle segments yellow.

Larvae feed on scabious. In experiments, the larvae have been shown to feed readily on cut-leaved teasel (Dipsacus laciniatus) which occurs in the British Isles as a bird seed or garden escape. Abia sericea larvae have a row of black dots on the dorsal midline.
