Swallow Prominent

Pheosia tremula

Fairly common throughout Britain, mainly nocturnal.

The Larvae feed on poplar (Populus) and sallow (Salix).

Normally whitish, with a brown shaded black stripe along the inner margin of the forewings, and a brownish cloud, with black streaks in it.

Towards the tips of these wings; the outer extremities of the veins are white, there is a white wedge-shaped streak between veins 1 and 2, and from the apex of this an indented white line runs to the base of the wing.

Sometimes the whole discal area is suffused with brownish.

Moth plentiful everywhere, in May and July—August.
