Pale Prominent Pterostoma palpina
Wingspan 35-55 mm.
A distinctive moth when at rest, though well camouflaged, it has long labial palps and tufts on the tail segment, creating an elongated appearance.
Occurring throughout much of Britain, it is most common in the south.
It flies in May and June, and in the south, again in August.
The larval foodplants are poplar (Populus), and sallow (Salix).
