Key Diagnostic or Identification
Approved Method(s)
ID/Diagnostic:
Morphological: Adults can be recognized by the black forewings with distinctive yellow, orange, and silvery markings. Male and female genitalia are also diagnostic. Descriptions of adult morphology can be found in Dang and Parker (1990).
Mistaken Identities:
In North America, Eucosmomorpha nearctica is similar in size and has a similar forewing pattern, but the two can be easily separated by male or female genitalia. See the Enarmonia formosana datasheet in the Stone Fruit Commodity Reference for a full list of non-target species caught in E. formosana traps.
