Broods/Flight Times: There is one flight. Nebraska records are from 19 June – 18 August. It undoubtedly flies earlier than June 19, but due to its rarity data is scarce. In South Dakota, where it is more numerous, Marrone (2002) reports it as occurring as early as June 6.

Notes: This, along with Edwards’ Fritillary, is one of the earlier flying Speyeria found in western Nebraska. Many years often pass between sightings. The most recent Nebraska records are 1969, 1997 and 2021 all single individuals.
