Coleophora glaucicolella

Alternative names
Grey Rush Case-bearer

Wingspan 10 to 12 mm. The adults resemble several other Coleophora species and are most reliably identified by dissection of the genitalia.

Identification difficulty

To be found close to areas with Juncus species of rush. It is often abundant on salt marshes.

When to see it

Flight period June to August at sunrise, dusk and night.

Life History

The full grown larval case is very similar to that of C. alticolella, but the larvae can be differentiated.

UK Status

Coleophora glaucicolella is widespread and common in Britain, but sometimes goes unrecorded because of confusion with another Juncus feeding species, C. alticolella. In the Butterfly Conservation's Microlepidoptera Report 2011 this species was classified as common.

VC55 Status

It appears to be uncommon in Leicestershire and Rutland, where there are few records. L&R Moth Group status = D (rare or rarely recorded).
