Abia aenea (Klug, 1820)

Abia aenea

Abia aenea is 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. Adults cannot usually be determined from images but specimens can be determined by antennal shape and the microsculpture of the mesosternum. The female of this species has more slender antennae, three times as long as broad, (viewed side on) and both sexes have dense microsculpture between the punctures on the mesosternum.

Larvae feed on honeysuckles and other members of the Caprifoliaceae. They are very similar in appearance to Abia lonicerae larvae but lack a black mark posterior to the spiracle (postspiracular lobe) on each abdominal segment. This mark is present in Abia lonicerae. Note: do not confuse with the black mark present on the suprapedal lobe at the top of each abdominal leg which is present in both species.

Size: approx. 12mm

Status: unknown

Distribution: England

Flight period: April to June

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