Coleophora semicinerea: feeding

opened pod Tripodion tetraphyllum with larva feeding on a seed (from Nel, 1994b)

parasite

The young larva devores the ovary of a flower, then uses the calyce (or, in case of a large flower, part of the calyce) in constructing the only case of its life. The mouth opening (angle hoek 20°-30°) is at the side op the peduncle. Within the calyce a trivalved cylindrical case is made from pale cream silk.

hostplants

Fabaceae, oligophagous

Anthyllis vulneraria; Colutea arborescens; Lotus edulis; Tripodion tetraphyllum.

phenology

The larva is full fed around end April (in Malta) and leaves to host plant to find a shelter in rock crevices etc.

distribution within Europe

Mediterranean Europe, including the Canary Islands (PESI, 2018).

notes

Coleophora semicinerea: worn case

During the long time that a larva is in diapause a case can worn so strongly that almost all plant tissue has been eroded away, leaving only the resistant silken case inside. The above picture shows such a worn case.
