Salix arctica, the Arctic willow, is the larva's primary host plant. G. groenlandica spends much of its life in a larval state, and food resources are necessary for development of the larvae. Salix arctica, the Arctic willow, is the primary host plant and food source for this species.
Arctic vegetation is largely controlled by the mean temperature in July, the warmest month. Arctic vegetation occurs in the tundra climate, where trees cannot grow.Tundra climate has two boundaries: the snow line, where permanent year-round snow and ice are on the ground, and the tree line, where the climate becomes warm enough for trees to grow.

In the Cronquist system, the Salicaceae were assigned to their own order, Salicales, and contained three genera, Salix, Populus, and Chosenia (now a synonym of Salix). Recognized to be closely related to the Violaceae and Passifloraceae, the family is placed by the APG in the order Malpighiales.
