Speyeria zerene

Observation date: July 29, 2025
Submitted by: mstanek
Specimen type: Photograph
Observation notes: None.
Status: Resident
Verified by: J_Martineau
Verified date: August 08, 2025
Coordinator notes: ssp. picta. Greater fritillaries of the west are tough with much intraspecific variation regionally. I lean on the Pelham List to identify (https://butterfliesofamerica.com/US-Can-Cat.htm). I'm not sure who is vetting sightings for Alberta, but I don't see submissions outside the area the site has assigned to me.
