Sallow Clearwing Synanthedon flaviventris

(Staudinger, 1883)

Wingspan 17-20 mm.

Only discovered in Britain in 1926, this species occurs locally commonly in parts of central southern England.

It inhabits woodland and damp places, and the moths are on the wing in June and July.

The larvae live in the stems of sallow (Salix), forming a distinctive gall. The species has a two-year life cycle, with adults present mostly in even years.
