Identification TipsDistinguished from the similar Swallow Prominent (*Pheosia tremula*) by its slightly smaller size and the shape of the dark streak on the forewing, which is typically more pointed and less extensive in *P. gnoma*. The 'swallow tail' appearance of the hindwing when at rest is characteristic of the genus.
Description
A medium-sized moth with mottled brown and white forewings, characterized by a prominent dark streak and a jagged outer margin, giving it a cryptic appearance.
