and Size:
Forewing length ranges 7.0-9.0mm. Two annual generations and adults are present from May to September.
Description/
Field Marks:
Forewing pattern is distinct and composed of a black ground color, with silver markings surrounding by orange and yellow lines (1). The ocellus is conspicuous with 3-4 thick black bands with thin yellow lines between them. The ocellus is surrounded with silver and orange lines. Forewing fringe is brown-black with 2-3 distinct yell-orange lines; 1-2 on the apical half of the termen, and 1 on the lower half, at the base of the ocellus.
Similar Species: Can appear similar to Eucosmomorpha nearctica which lacks the black forewing ground color (1). The defined ocellus of E. formosana distinguishes this species from similar looking Olethreutes. Genitalia can also be used to delimit species (1)
