| Speyeria callippe calgariana (McDunnough, 1924) |
| Status: Rare to uncommon resident. Fewer than a dozen have been reported from the state, and decades often pass between sightings. |
| Flight Period(s): 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. |
| Range: The Callippe Fritillary is found from southern portions of British Columbia to Manitoba south through most of California, Nevada, Utah and Colorado. In Nebraska it is recorded from Sioux and Banner counties. |
| Larval Hostplant(s): Violets, of which Yellow Prairie Violet (Viola nuttallii) has been observed as a host and occurs in the areas where this fritillary has been found. |
| Overwinter: As an unfed caterpillar |
| Commentary/Habitat: This, along with Edwards’ Fritillary, is one of the earlier flying Speyeria found in western Nebraska. In South Dakota, where it is more numerous, Marrone (2002) reports it as occuring as early as June 6. The most recent Nebraska records are from Wright’s Gap south of Melbeta ( Banner County) 28 June 1969, and along the Pants Butte/Sowbelly Canyon Road ( Sioux County) 6 July 1997, the latter being a female, and nectaring on hairy verbena. Earlier records are from Squaw, Warbonnet and Monroe Canyons ( Sioux County). |
