Coleophora glaucicolella Wood, 1892
grey rush case-bearer
The young larva lives within a fruit, consuming the seeds. Only in its second instar it starts constructing a tubular silken case, gradually increasing in length. The final is is pale buff to greyish, 5-6 mm long, with a mouth angle of 0°-10°.
Juncus articulatus, conglomeratus, effusus, gerardi, inflexus, maritimus.
A reference to Juncus bufonius by Zimmermann & Skala possibly applies to Coleophora lassella.
Larvae that still need to feed after hibernation are sometimes found on Luzula multiflora.
Larvae from September; hibernation as (generally full-fed) larva; pupation in June-July,
still in the case.
distribution within Europe
Cases and larvae are indistinguishable from those of C. alticolella. However, as appears from the list of host plants, more a species of saline habitats.
