Abia aenea (Klug, 1820)

Abia aenea

Very similar to the more frequently encountered Abia lonicerae. Both species share the same habitat and foodplants, but the larvae are apparently different in appearance. Adult specimens can be determined by antennal shape and the surface of the mesonotum. This species has more slender antennae and microsculpture between the punctures on the lateral faces of the mesonotum.
Larvae feed on honeysuckles and other members of the Caprifoliaceae.

Size: approx. 12mm

Status: unknown

Distribution: England

Flight period: April to June

Plant associations: Lonicera spp., Symphoricarpos spp. and Leycestria spp. (honeysuckles, snowberry and pheasantberry)
