North American Ecology (US and Canada) ( 英語 )

由North American Butterfly Knowledge Network提供
Oeneis alberta is native to southern Canada from Alberta to Manitoba, with many small separate populations scattered through the central United States (Scott 1986). Habitats are dry bunchgrass hills. Host plant is bunchgrass. Eggs are laid singly. Individuals overwinter as older larvae; species is possibly biennial. There is one flight each year with the approximate flight time May 15- June 15 (Scott 1986).

General Description

由University of Alberta Museums提供
The upperside is dull ochre-brown, with a variable number of small black eyespots, usually two on the forewing and one on the hindwing. The underside is finely striated black and white, with a distinct hindwing median band. The hindwing veins are outlined in white, unlike O. uhleri. The nominate subspecies (described from the mouth of Fish Creek near Calgary) occurs throughout southern Alberta. The Peace River populations are a darker, unnamed subspecies (Bird et al. 1995). cc-by-nc

Life Cycle

由University of Alberta Museums提供
"In the Peace River grasslands, the barrel-shaped eggs are laid on the tips of grass blades, and hatch in about 30 days. Larvae are reddish-brown with short, conical 'tails', and overwinter in the 5th instar, pupating early in the spring without further feeding. Pupation occurs in grass clumps near the ground. Males patrol territories to locate females, and will also fly to geographical prominences such as hilltops (Bird et al. 1995). Although sites that support Alberta Arctics almost inevitably also support Uhler's Arctics, O. alberta tends to be more localized and less widespread in distribution."

Trophic Strategy

由University of Alberta Museums提供
Larval food plants are unconfirmed, though fescue (Festuca) is a likely host (Scott 1986, Bird et al. 1995).

Oeneis alberta ( 英語 )

由wikipedia EN提供

Oeneis alberta, the Alberta Arctic, is a butterfly of the family Nymphalidae. It is found from the Canadian prairie provinces east to southern Manitoba. Isolated populations are found along the Rocky Mountains in Colorado, New Mexico and Arizona.[2]

The wingspan is 35–57 mm. The upperside is light yellow grey while the underside is light brown. Adults are on wing from May to June in one generation per year.

The larvae feed on bunch grass, possibly Festuca species. The species overwinters in the larval stage.

Subspecies

  • Oeneis alberta alberta (Manitoba, Saskatchewan, Alberta, British Columbia, Montana, North Dakota)
  • Oeneis alberta oslari Skinner, 1911 (Colorado)
  • Oeneis alberta capulinensis F.M. Brown, 1970 (New Mexico)
  • Oeneis alberta daura (Strecker, 1894) (Arizona)
