Last modified: Feb. 20, 2022, 4:25 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.
