Identification


ID/Diagnostic: Morphological

Morphological: There are 13 world species in the Diprion genus. All Diprion are very similar in general appearance and examination of the female ovipositor and male genitalia are the most reliable means for separation of the species.
Mistaken Identities:
The genus Diprion is most similar to species of Neodiprion and Gilpinia. Species of Gilpinia are the most similar-looking; species of the two genera are often confused. For a key separating North American genera of Diprionidae, see Smith (1974). Similar species that may show up in traps in the United States are species of Neodiprio, Diprion similis, Gilpinia hercyniae, and Gilpinia frutetorum.
