Red-tipped Clearwing Synanthedon formicaeformis
Wingspan 17-19 mm.
This moth derives its English name from the reddish patches at the tips of the forewings.
It can be found locally throughout much of England, southern Scotland, south Wales, and scarcely in parts of Ireland, and flies between May and July.
The species inhabits fens, marshes and other damp localities, and feeds as a larvae inside the stems of various species of Salix, especially osier (S. viminalis).
