Case-bearing Clothes Moth Tinea pellionella
Linnaeus, 1758Wingspan 9-16 mm.
One of the 'clothes moths', this species is widely distributed over the British Isles.
The larvae feed in a portable case, on such things as wool and fur, but also feathers and in birds' nests.
The adults are generally on the wing between June and October, but may appear outside this period since they often live inside buildings.
