Coleophora alticolella Zeller, 1849

common rush case-bearer

on Juncus

Coleophora alticolella: case

case (from Patzak, 1974a)


Larva initially hidden in a fruit, of which the seeds are consumed. From here it starts making a whitish or grey tubular silken case, in which it later crawls freely over the inflorescence. The completed case is 5-6 mm long with a mouth angle of 0°-5°.


Juncaceae, monophagous

Juncus articulatus, conglomeratus, effusus, inflexus, squarrosus.

At high densities sometimes a larva strays towards Luzula campestris.


Cases from about August. Hibernation as larva in the case; pupation in May-June, still in the case.

distribution within Europe

All of Europe.


The case cannot be distinguished from the one of C. glaucicollela, that has the same biology and hostplants. The differences in the larvae, mentioned by Emmet ao, based on an old paper by Wood are not convincing.
