Small Seraphim Pterapherapteryx sexalata
Wingspan 22-26 mm.
Distributed mainly in the south and east of England, it also occurs locally in a few scattered places elsewhere in Britain.
In southern England there are usually two generations, flying in May and June, and then in July and August; otherwise there is just one brood appearing in June and July.
The preferred habitats are woodland, hedgerows, fens and similar marshy places.
Sallow (Salix) is the larval foodplant, the caterpillars feeding in the autumn.
