Global Range: (200,000 to >2,500,000 square km (about 80,000 to >1,000,000 square miles)) Range includes the Coast, Cascade, Rocky, and Sierra Nevada Mountains of North America (Stewart and Oswood, 2006).

Habitat Type: Freshwater

Comments: It occurs in creeks and small rivers (Gaufin et al., 1972).

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: > 300

Comments: Gaufin et al. (1972) cite Montana distribution as Flathead, Gallatin, Granite, Missoula, and Ravalli Cos. A record of Alloperla delicata from Box Elder Co., Utah, is actually Alloperla severa (Baumann, 1973). Recently, specimens were discovered in Mount Rainier National Park in Pierce Co., Washington (Kondratieff et al., 2006). In California, Jewett (1960) cited Sierra Co. In western Canada, Stewart and Oswood (2006) cite Alberta and British Columbia; with unconfirmed records from Alaska (Angel Creek, Denali National Park, North Fork Chena River).

Unknown

Adults emerge from April to August (Gaufin et al., 1972).
