Coleophora caespititiella: case

case (from Patzak, 1974a)


The young larvae for quite some times lives hidden within a fruit, feeding on the seeds. Only in its penultimate instar it begins making a case. The final cage is well hidden and camouflaged between the fruits. It is a greyish brown trivalved tubular silken case with a mouth angle of 10°-40°; the frass is covered with much “dirt”, frass grains and plant detritus.


Juncaceae, monophagous

Juncus articulatus, conglomeratus, effusus, gerardi, inflexus, squarrosus.


Cases from end August till about the end of September. The full fed larvae leave the host plant towards the surrounding vegetation, then enter diapause and pupate in the following spring, all the time in their cause.
