The wings are held close to the body at rest, steeply angled. They are very similar in appearance to the Lesser Swallow Prominent but can be distinguished by the white wedge on the trailing edge of the forewing which is longer, narrower and more greyish-white in the Sallow Prominent.

The larvae can be seen from June to July and late August to September which then overwinter underground as pupae.
