Coleophora kuehnella (Goeze, 1783)
white oak case-bearer
Quercus robur, Vlaardingen
The full grown larva lives in a black pistol case of c. 8 mm, with a mouth angle of c. 90°. The case is covered by a silken mantle (pallium) that hangs from its rear end, and almost covers the case, giving it the general aspect of a bird dropping. The larve mines the leaf from the underside, making many, unusually small fleckmines, up to about 30 together.
Quercus robur, rubra.
Larvae are full grown in early June (Emmet ao, 1996a).
BE recorded (Phegea, 2010).
NE recorded (Kuchlein & de Vos, 1999a; Microlepidoptera.nl, 2010).
LUX not recorded (Fauna Europaea, 2010).
distribution within Europe
From Fennoscandia to Iberia, Sardinia, Italy, and Albania, and from Britain to South Russia (Fauna Europaea, 2010).
Described by Emmet ao (1996a); there are three pairs of abdominal prolegs.
Coleophora palliatella (Zincken, 1830).
If the youth case that is illustrated below really belongs to kuehnella is far from certain, but at least it belongs to the group “pistol case with pallium”.
