Last modified: June 17, 2024, 12:28 p.m.
Coleophora virgaureae has long been considered a synonym of Coleophora obscenella. However, Baldizzone & Tabell (2002) recognized these as distinct species. The first record, with the correct name Coleophora virgaureae, dates back from 1862 when cases were found on Solidago virgaurea at Groenendaal (Hoeilaart).
A very rare and local species in the southern part of Belgium, mainly known from the Calestienne.

Caterpillar
Body dirty white, head is blackish brown.
Case
The larvae live in a 5–6 mm long, tri-valved, dark brown, silken case. The early case is light brown but changes rather quickly into dark brown. Therefore it is hard to find between the seed heads of the plant which have the same colour.
The mouth angle is 40–70°.
