North American Ecology (US and Canada)

Speyeria hydaspe is resident to the northwestern United States (Scott 1986). Habitats are moist dense woodland. Host plants are herbaceous, restricted to several species in genus Viola. Eggs are laid haphazardly, near the host plant, singly. Individuals overwinter as unfed, first instar larvae. There one flight each year with the approximate flight time June 1-Sept. 30 (Scott 1986).

Distribution
provided by University of Alberta Museums
The core of Hydaspe's distribution is the Pacific Northwest, ranging north to central BC and the mountains of southern Alberta, and south to Colorado and California (Scott 1986). There is an isolated population in the Cypress Hills of Saskatchewan (Layberry et al. 1998), so it should be watched for on the Alberta side of the Hills.

General Description
provided by University of Alberta Museums
The hindwing underside is diagnostic; no other Speyeria has a maroon-brown underside with creamy-white in place of the usual silvery-white discs. Subspecies rhodope occurs in Alberta (Kondla 2001).

Life Cycle
provided by University of Alberta Museums
The mature larvae are black and spiny, and lack pale markings (Guppy and Shepard 2001). In the US, first-instar larvae hibernate without feeding (Scott 1986). This species prefers cool/moist coniferous forests of the mountains to the dry grasslands inhabited by most other Speyeria.

Trophic Strategy

The larvae feed on violets (Viola sp.) (Guppy & Shepard 2001), and adults are attracted to yellow composite flowers (Bird et al. 1995).

Speyeria hydaspe
provided by wikipedia EN
Speyeria hydaspe, the Hydaspe fritillary, is a species of orange-brown butterfly found in the western portions of the United States and Canada. A small fritillary, it usually has cream-colored underwing spots, but the Vancouver Island subspecies has silver spots. It is similar to S. zerene and S. atlantis, but may be distinguished by the smooth and even appearance of its postmedian spotband.[2] The caterpillars feed on violets including Viola glabella. A single brood flies from July through September and feeds on flower nectar. They may be found in moist forests, in clearings and subalpine meadows. [3]
