Coleophora glaucicolella

Description

Coleophora glaucicolella is a moth of the family Coleophoridae. It is found from Europe, east to the Urals and Iran, west to Greenland and North America (where it is found in most of Canada and Ohio). It is also found in China. It occurs in forest-steppe biotopes, wet meadows and meadow-steppe. The wingspan is 10–12 mm. Forewings pale and often yellowish or ochreous - tinged, usually with darker greyish streaks between veins towards costa. Only reliably identified by dissection and microscopic examination of the genitalia. Adults are on wing from June to August at sunrise, dusk and night. The larvae feed on the seeds of Juncus species, including Juncus inflexus, Juncus conglomeratus, Juncus effusus and Juncus gerardii, and supposedly also on Luzula. They create a trivalved, tubular silken case.
