    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
