Coleophora badiipennella: youth mine on Ulmus

Ulmus spec., Nijeveen, 6.ix.2019 © Ben van As: youth mine; length of the excision 3.8 mm


The final case is a small, laterally compressed, squat, spatulate leaf case of 5-6 mm. The dorsal keel often has some serrations, remnants of the leaf margin out of which the case was cut. The rear is two-valved, and remarkably broad. The mouth angle is 0-10°.

The description and illustration of the final case in Emmet ao (1996a) is not quite clear. They depict a rather slender case, and state that the mouth angle is 30°. But, as the only illustration in the other literature that would agree with the British badiipennella, they refer to Hering (1957a, fig. 701): this illustration, however, has no resemblance to their own figure, and has a mouth angle of c. 0°.

Emmet ea write that the larva begins its life by making a gallery of 10-15 mm that runs from the midrib along a side vein; out if this mine the first youth case is excised.

host plants

polyphagous on woody plants

Acer campestre, platanoides; Corylus avellana; Fraxinus; Ulmus glabra, x hollandica, minor.

In Britain exclusively on Ulmus (Emmet ea, 1996); probably also elsewhere this is the most important hostplant. References to Rosaceae (in particular Prunus spinosa) are connected probably with C. adjectella, that often has been understood as a subspecies of badiipennella.


The larvae are full fed in September – October, but often continue feeding in spring (Emmet ao, 1996a).


BE recorded (Phegea, 2010).

NE recorded (Kuchlein & de Vos, 1999a;, 2010).

LUX not recorded (Fauna Europaea, 2010).

distribution within Europe

From Fennoscandia to the Mediterranean, and from Britain to South Russia (Fauna Europaea, 2010).


The larva is described and illustrated by Suire (1961a).


Mainly on seedlings.
