Pamphilius fumipennis (Curtis, 1831)

Pamphilius fumipennis

Predominantly black with yellow legs. The antennal scape is entirely yellow (unlike in the similar Pamphilius sylvaticus).

Pamphilius fumipennis larvae feed singly in leaf rolls rolled towards the underside. On the continent, grey alder is the preferred foodplant but in Britain the associate foodplant is usually hazel. Grey alder is now widely planted in Britain in amenity landscaping projects.

Size: 8 - 11mm

Status: Uncommon

Distribution: England, Wales

Flight period: May to June

Plant associations: Corylus avellana and Alnus incana (hazel and grey alder)
