(1) list as
Basilarchia arthemis astyanax, apparently a new name.
Explanation of Names
See below for explanation of common names of the three forms.
Numbers
three forms (not subspecies, apparently)--see below
Identification
White Admiral (Limentis arthemis form arthemis) - the northern form, basically black and white in the east:
In the west specimens tend to have red spots on the hind wing and are called Western White Admirals (Limentis arthemis form rubrofasciata):
In the SE USA and as far north as extreme southern Ontario this species is black and purple (no white band)and is called Red-Spotted Purple (Limentis arthemis form astyanax):
As the 3 forms are regarded as being the same species, intergrades between them are quite common.
Red-Spotted Purple mimics the
Pipevine Swallowtail, but its hind wings lack the tails and Pipevine lacks spots at wing base. Compare Pipevine Swallowtail:
Food
Larvae feed on cherry, willow, birch and some other trees and shrubs. Adults will take moisture from mud puddles, rotten fruit and animal feces.
