A nice female Colias eriphyle

Norbert Kondla

Here is a nice female eriphyle specimen from Mount Cole, British Columbia:
The color is atypical. Here are some ways that different people would identify this butterfly:
Colias eriphyle
Colias philodice eriphyle
Colias eurytheme
not even a species or subspecies; it is just a species in statu nascendi, aka semi-species, aka incipient species
