Speyeria callippe callippe

Callippe Fritillary

Speyeria callippe callippe is a of fritillary in the Nymphalidae. It belongs to the greater fritillary Speyeria, which includes known for their close ecological association with violets (Viola spp.) as larval plants. The subspecies is native to western North America. Related Speyeria species have been demonstrated to rely primarily on visual cues for navigation to suitable patches.

Identification

As a of Speyeria callippe, S. c. callippe would be distinguished from other S. callippe subspecies by subtle differences in wing coloration, pattern, or size. The Speyeria callippe as a whole can be distinguished from similar fritillaries by the silvery spots on the undersides of the wings. The subspecies S. c. callippe is the nominate subspecies, meaning it represents the typical form of the species.

Habitat

Based on distribution records, this occurs in prairie and open woodland in the Canadian provinces of Alberta, Manitoba, and Saskatchewan. Speyeria generally require habitats containing larval plants (violets) and nectar sources for .

Distribution

Recorded from Alberta, Manitoba, and Saskatchewan in Canada. The Speyeria callippe has a broader range in western North America.

Host Associations

Viola - larval plantBased on -level trait: Speyeria larvae feed on violets. Specific plants for this not documented in provided sources.

Behavior

Research on congeneric (Speyeria cybele and Speyeria atlantis) demonstrates that Speyeria butterflies rely primarily on visual perception for navigation to suitable patches. Flash-blinded individuals showed dramatically reduced ability to locate target habitat, even at distances as short as 20 meters. Whether S. c. callippe exhibits identical navigation has not been specifically tested.

Human Relevance

The related Speyeria callippe hagemani was named in honor of collector Chuck Hageman (1945-2021) of Yuba City, California, recognizing his extensive field research on California butterflies. Specimens of that subspecies are deposited at the Los Angeles County Museum of Natural History.

Taxonomic Note

GBIF records indicate this is accepted and occurs in the Canadian prairie provinces. The Speyeria callippe contains multiple subspecies with distinct geographic ranges in western North America.

Research Context

While specific studies on S. c. callippe navigation have not been published, research on Speyeria cybele and S. atlantis by MacDonald et al. (2019) established that visual perception is the primary sense used for detection in this . Flash-blinded butterflies in that study showed only 11% success rate in reaching target islands, compared to 80-85% success at 30-40 meters for unaltered individuals.
