Coleophora conyzae case

Pulicaria dysenterica, Belgium, prov. West-Flanders, Adinkerke, Westhoek reserve © Steve Wullaert


Larva in a spatulate leaf case, at the underside of the leaf. The case is 10-12 mm long, straight, brown, tubular, laterally compressed, patently hairy (depending on the host plant), bivalved. The mouth angle is rather variable, usually around 45°. A peculiar character of this species is that after each moult the larva makes a new case; the old, vacated case is left at the place where the new one is made, at the leaf margin.

host plants

Asteracee, oligophagous

Dittrichia viscosa; Eupatorium cannabinum; Inula conyzae, ensifolia, hirta, oculus-christi, salicina, spiraeifolia; Pulicaria dysenterica.

On Crete larvae have been found on Ruta (Baldizzone, 1990b); for the moment this seems xenophagy.


The larva is full grown in end May, early June (Emmet ao, 1996a).


BE recorded (Wullaert, 2010b).

NE recorded (Kuchlein & de Vos, 1999a;, 2009).

LUX not recorded (Fauna Europaea, 2009).
