I just noticed that INaturalist uses Argynnis cybele as the name of the Great Spangled Fritillary, which I have always known as Speyeria cybele. Curious, I went to BugGuide to look for additional information and found this statement on the Speyeria genus page - " Historically, and often still, Speyeria and Fabriciana (and most other “Greater Fritillaries”) have been included within an expansive concept of the closely related Eurasian genus Argynnis.
Since I have know both BugGuide and INat to stay on top of taxonomic changes, I am really curious if anyone can shed some light on the current concepts of these genera. Thanks!
