Coronis Fritillary
Speyeria coronis

Observation date: August 12, 2024
Submitted by: Cascade Colors
Specimen type: Photograph
Observation notes: None.
Status: Resident
Verified by: mikefisher
Verified date: September 15, 2024
Coordinator notes: I am going to agree with your suggested ID as Coronis but based solely on what looks like to me to be the small marginal spots at the edge of the hindwing...they look rather flat or "lens-shaped" which Colorado Coronis tend to characteristically have...no color on the underside at all so the color of the caps on these spots cannot be used for ID...they are brown on Coronis and green on zerene...this is less so reliable in western Colorado where some coronis can have greenish wing discs on the underside...then these spots may be brownish, greenish or a mixture. The less heavy markings on the upperwing you can see are also seem to suggest Coronis. Mike
