Submitted by: Cascade Colors
Specimen type: Photograph
Observation notes: None.
Status: Resident
Verified by: mikefisher
Verified date: July 08, 2022
Coordinator notes: This is a female Margined White. Great Southern White is a much larger butterfly (2-1/2" or more in wing expanse) and there is one report of it in Colorado many years ago but no extant specimen or photograph, and no verification of any others since (the GSW was very common in southern Arizona last late summer with the super monsoon they had then...otherwise also usually rare in that area).
