Atlantis Fritillary
Speyeria atlantis

Observation date: July 18, 2013
Submitted by: M Mimura
Specimen type: Photograph
Observation notes: None.
Status: Resident
Verified by: mikefisher
Verified date: December 04, 2013
Coordinator notes: I am reasonably confident this is a female of Speyeria atlantis (ssp. sorocko for "Southern Rocky Mountains"). No locality information is given but I am going to guess that it was around Telluride in the San Juan Mts. where I have also found this this fritillary. The often co-inhabitor also occurs with it Speryeria hesperis (Northwestern Fritillary) but the markings on this example are a little bit more delicate and the color more typical to S. altantis than that fritillary.
