Abia candens

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

Larvae feed on members of the Dipsacaceae family which includes scabious species. Eggs are deposited into pockets cut along the edge of the leaf blade. Each pocket may be expanded to accommodate an additional egg. Eggs develop for two weeks. The larvae develop over a three to four week period. A cocoon is made below ground. Abia candens larvae lack a row of black dots on the dorsal midline and have an entirely pale suprapedal lobe.
