Euphydryas chalcedona

Euphydryas chalcedona is resident of the western United States and Canada, From Alaska to southern Calif., and east to Colorado (Scott 1986). Habitats are upper Sonoran to alpine zone desert hills, chaparral, open forest and alpine tundra. Host plants are herbs and shrubs with hosts including species from many families, including Scrophulariaceae, Valerianaceae, Orobanchaceae, Planaginaceae, Caprifoliaceae, and occasionally Boraginaceae, Labiatae, Rosaceae and Loganiaceae. Eggs are laid on the host plant in large clusters. Individuals overwinter as third and fourth instar larvae in litter or under rocks, and can hibernate for several years. There is one flight each year with the approximate flight time April 1- April 30 in the southern part of the range and late June ? July 15 in the far north. In western Arizona there are several flights from April 1-Oct. 31 (Scott 1986).

Global Range: (>2,500,000 square km (greater than 1,000,000 square miles)) W. North America from Alaska to Mexico, between Cascades, Sierra Nevada and the Great Plains.

Comments: General, coastal to alpine and sagelands. Larval hosts are various members of the families Scrophulariaceae, Plantaginaceae, Boraginaceae.

Non-Migrant: No. All populations of this species make significant seasonal migrations.

Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).

Locally Migrant: No. No populations of this species make annual migrations of over 200 km.

Note: For many non-migratory species, occurrences are roughly equivalent to populations.

Estimated Number of Occurrences: 81 to >300

10,000 to >1,000,000 individuals

Males both perch and patrol for females (Scott, 1986).
