Coleophora badiipennella
(Duponchel, [1843])
Wingspan 9-11 mm.
Locally distributed throughout much of England, the adults fly in June and July and occasionally come to light.
The larva constructs a case from a fragment of a leaf of the foodplant, elm (Ulmus), after mining a narrow gallery.
It occurs around the edges of woodland and prefers saplings to mature trees.
