Description
Normally whitish, with a brown shaded black stripe along the inner margin of the fore wings, 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. The imago can be easily mistaken with Pheosia gnoma.
The host plant of the Swallow Prominent are the poplar, especially the aspen, the willow and the birch. For detailed list see Robinson, G. S., P. R. Ackery, I. J. Kitching, G. W. Beccaloni & L. M. Hernández, 2010.
