Confusion Species: Coleophora glaucicolella (Grey Rush Case-bearer)

Distribution: Uncertain as this species cannot be identified without a Gen Det – only confirmed records come from Harrison & Sterling 1986 – Repton and Goyts Moss – Current records of larval cases are aggregated as C.alticolella-glaucicolella. 9 records on irecord – latest aggregated record 2/3/2025 Markham Vale.

Flight Period: June / July / - Sunrise, dusk and into the night

- The larvae feed on Juncus spp (Rush) After feeding initially inside a seed they construct a silken case covered with seed fragments. The larvae hibernate and pupate on the ground. Larval cases are indistinguishable from those of C. glaucicolella so gen.det of bred moth is required.

Moth Activity: Cathemeral - active from dusk into the night

Photographed: No - Photographed By: Not Recorded
