Coleophora virgaureae Stainton, 1857

golden-rod case-bearer

on Galatella, Solidago, (Tripolium)

Coleophora virgaureae: case

case (from Patzak, 1974a)

parasite

The larva in a 5-6 mm long, trivalved, dark brown cylindrical silken case with a mouth angle of 40°-70°. The larvae feed upon the fruits. As the picture above shows, fragments of the pappus are incorporated in the case. These fragments may be expected to erode anyway in the course of the winter.

host plants

Asteraceae, oligophagous

Galatella sedifolia; Solidago virgaurea; Tripolium pannonicum subsp. tripolium.

Mainly on Solidago; perhaps only occasionally on Tripolium.

distribution within Europe

Europe, except the Mediterranean area (PESI, 2018).

larva

The larvae of obscenella and virgaurea are clearly different. In virgaurea the head is dark brown and the thoracic sclerites are strongly chitinised and sharply defined.
