Coleophora deauratella Lienig & Zeller, 1846

red-clover case-bearer

on Trifolium

parasite

The larva bores through the florets of a capitulum and feeds on the green seeds from the young pods. Not until in the fourth instar a case is spun from silk; this happens within floret. The finished case is dark reddish brown (except for the white trivaled rear end), ± 6 mm long, rather stout-tubular; the front half of the case is wrapped in a dried floret. When the larva is feeding the white end of the case points conspicuously forwards from the inflorescence.

hostplants

Fabaceae, monophagous

Trifolium medium, ochroleucon, pratense.

Often, but incorrectly, associated with Centaurea and other Asteraceae.

phenology

Cases from mid-August. The larvae are full fed in September. Pupation in the following spring, still in the case.

distribution within Europe

Entire Europe (PESI, 2018).

larva

Coleophora larvae

Comparison of the dorsal sclerites in three species with a comparable biology: C. deauratella (a), C. paramayrella (b), and C. mayrella (c) (from Nel, 1993b).
