The species was described by Harrison in 1942. Like other members of its , it is likely associated with temperate forest and woodland , though specific ecological details remain poorly documented. The genus Epirrita contains several species that are challenging to distinguish morphologically.

Identification

Members of the Epirrita are notoriously difficult to identify to level based on external alone. Epirrita undulata is distinguished from primarily through subtle differences in wing pattern, particularly the degree and form of the wavy transverse lines on the forewings that give the species its name (undulata = wavy). Genitalia dissection is typically required for definitive identification. The species lacks the more pronounced markings seen in some related Epirrita species.

Distribution

North America. Distribution records indicate presence in this region, though specific range details beyond continental occurrence are not well documented in available sources.

Taxonomic note

The Epirrita has undergone taxonomic revision, with several historically difficult to distinguish. The specific epithet 'undulata' refers to the wavy wing pattern characteristic of this species.
