|scientific name Callophrys niphon |
common name Eastern Pine Elfin
Open jack pine (Pinus banksiana) woodlands.
The single yearly brood flies in May and June, peaking in late May.
The Western Pine (C. eryphon) is the only other elfin with a 'busy' hindwing underside, with more than just the single median band found in other elfins. The Eastern has a more irregular, white-edged median band on the hindwing underside, and the outer edges of the submarginal arrow-shaped marks do not reach the wing edge as they do in eryphon.
Our populations are most similar to subspecies clarki Freeman (Bird et al. 1998).
The larva is pale green with a dorsal white stripe and a dorsal white patch near the head and the dark brown pupae overwinter (Bird et al. 1995). Adults, particularly females spend a considerable amount of time perching on branches of young pine trees, and one way to search for Eastern Pine Elfins is to tap the young trees and watch for elfins to fly out (Bird et al. 1995).
Not of concern.
In Alberta, the Eastern Pine Elfin is associated with jack pine, the presumed larval host plant (Bird et al. 1995). Adults take nectar at flowers (Layberry et al. 1998).
Primarily an eastern-boreal species, at the western edge of its range in northern Alberta and northeastern BC (Layberry et al. 1998, Guppy & Shepard 2001).
