scientific name    Satyrium fuliginosum    

common name     Sooty Hairstreak

habitat
Dry montane meadows. Should be looked for near lupines.

seasonality
June 25 is the only Alberta date. To be expected from late June to early August.

identification
This hairstreak is unusual in that it looks and acts more like a blue than a hairstreak. Both sexes have an unmarked, brown dorsum, and are most likely to be confused with female blues, particularly Boisduval's Blue (Icaricia icarioides). Sooty Hairstreaks, however, lack the flush of metallic blue-green scales at the base of the hindwing underside found in Boisduval's; the ventral forewing markings of fuliginosum are also more faint. Subspecies semiluna Klots presumably occurs in Alberta (Bird et al. 1995).

life history
The immature stages are undescribed. Presumably overwinters in the egg stage (Guppy & Shepard 2001). The Sooty hairstreak is rare to uncommon throughout its range (Layberry et al. 1998). Unlike other hairstreak species, males of the Sooty exhibit patrolling rather than perching behaviour to locate females.

conservation
The status of this species in Alberta is unknown since it has not been seen here since 1925.

diet info
Based on observations of females ovipositing on lupines (Lupinus spp.) in the US, this is the presumed larval foodplant throughout the range (Guppy & Shepard 2001).

range
Occurs from extreme southern BC (Okanagan valley) and AB south to northern California and Colorado (Opler 1999). The Alberta record is based on a single specimen collected near Waterton Lake in 1925 (Bird et al. 1995).
