Coleophora sylvaticella: case

case (from Patzak, 1974a)


The larvae appear around June. For a relatively long time they live free on the inflorescence, feeding on the ripening fruits. Only late in their development they start making a case. This is a tubular silken case, trivalved and 5-7 mm long, with a mouth angle of 20°-25° and a distinct neck just behind the mouth. For its first half or two thirds the case is covered by the tepals of its host plant flowers (therefore being, according to the definition, a seed case).

host plants

Juncaceae, (narrowly?) monophagous

Luzula sylvatica.


Before the hibernation the larvae leave their host plants and walk several meters away, sometimes crawling high upon trees, then enter diapause. Most larvae extend the diapause for an extra summer and winter. In April-May then follows the pupation, still within the case.

distribution within Europe

West and Central Europe; missing from the Iberian Peninsula and the Balkan Peninsula (PESI, 2018).
