Specimen type: Photograph
Observation notes: None.
Status: Resident
Verified by: mikefisher
Verified date: August 31, 2014
Coordinator notes: The male Colias eurytheme you correctly identified along with the female previously. Again, this looks like most spring eurytheme, some of which have much narrower black wing borders than this one which is kind of between spring and summer.
