Identification
ID/Diagnostic: Morphological
Morphological. Looks similar to the native species, P. rapae, but much larger (wingspan of 63 mm versus 48 mm). P. rapae males have a black spot on the forewing. Caterpillars of P. brassicae and P. rapae can be easily distinguished as their colorings are distinctively different.
Mistaken Identities:
Superficially, P. rapae (present in U.S.).
