Coleophora lassella: case on Juncus bufonius

case (from Nel, 1993c)


The larvae starts by consuming the contents of a fruit, without any evidence at the outside. When the larva becomes larger, a case becomes needed. The completed case resembles the one of C. insulicola, with a mouth angle 20°-30°.

host plants

Juncaceae, narrowly monophagous

Juncus bufonius.


The full fed larva leaves the host plant, hibernates, and pupates within the case in the spring.

distribution within Europe

Probably all Europe (PESI, 2018).
