Hantsmoths

Common in a wide range of habitats throughout much of the British Isles. In Hampshire confined to sites such as Chandlers Ford, Botley Wood, Emer Bog, Havant Thicket and Wickham Common in the south, and Winnall Moors, Harewood Forest, Pamber Forest, Odiham Common and Yately Common in the north. Not recorded from the Isle of Wight to date. Wingspan 12-16 mm. A slightly larger species than E. immundana and with generally lighter coloration; in E. tetraquetrana the medial angulation of the outer edge of the basal patch is obtuse, whereas in E. immundana it is acute [Bradley]. Larva feeds within bark of Birch and Alder, forming galls, over-wintering as a pupa in a cocoon.
