Tinea cribrella Hübner, 1796The Thistle Ermine, Myelois circumvoluta, is a small moth species of the family Pyralidae. It is found in Europe.
This pyralid has a pattern of black dots on its whitish forewings, resembling many ermine moths (family Yponomeutidae). Among the Lepidoptera, the pyralids and the ermine moths are not closely related, however: the latter are basal Ditrysia, while the former belong to the much more advanced Obtectomera.
The wingspan is 27–33 millimetres (1.1–1.3 in). The moth flies in one generation in late spring to early summer, e.g. from the end of May to June in Belgium and The Netherlands.
The caterpillars feed on Cynareae thistles – Greater Burdock (Arctium lappa), Cotton Thistle (Onopordum acanthium), and Carduus and Cirsium species.
