Field Marks:
Forewings with “considerable variation in the delineation of beige markings on the cream background”. Males tend to have more conspicuous coloration and also dark hair tufts (sex scales) at the base of the costal margin. Both sexes have two white spots surrounded by orange-brown scales on the upper half of the wing, in the middle. A dark brown oblique streak can be seen on the posterior margin of the wing; more noticeable in males. Hindwings white, with light brown scales near the apex.
Similar Species:
  • This species has a distinct wing pattern that can reliably confirm identity. Evergestis may appear similar to C. pavonana however, North American Evergestis lack the distinct paired white orbicular spots
  • Pinned specimens of related species. (Hint: select View by Region on the related species page.)
