|scientific name Gypsonoma parryana |
Inhabit boreal forest regions with occasional occurrence in small forested patches within the grasslands (Pohl et al. 2010).
Adult flight periods occur in June (Pohl et al. 2010).
This genus has a forewing pattern that is uniform with the basal patch and median fascia well defined. This well defined region is also separated by an interfascial band of contrasting, lighter coloration. Male moths lack costal folds and notching near the base of their antennae. Male genitalia consist of a prominent clasper on the basal excavation margin and a cluster of long scales on the tegumen (near the area where the tegumen articulates with the vinculum). Female genitalia consist of two tacklike signa with some degree of sclerotization of the ductus bursae. The sculpturing of the sterigma is different between species (Heinrich 1923, Miller 1987, Gilligan et al. 2008).
This species has an alar expanse of 16-17mm. The forewings are pale yellow-brown to brownish, brownish grey or greyish in coloration. The costal strigulation is indistinct with darker dividings and markings on the wings are rust-brown, grey or similar. The basal blotch can be distinct but is often weak and diffuse. The median fascia is also weak and usually diffuse with the dorsal end atrophied. Cilia are the same color as the ground color of the forewings. The periphery of the hindwing is creamy brown or brownish grey with pale, creamy or whitish grey ciliar. The ground color can vary in shade and intensity of coloration. Markings are similar or can be more brown or tinged with grey or rust (Razowski 2003). Male genitalia have a ventral edge of the sacculus half the length of the valva. The caudal angel is weak and the ventral incision shallow. The ventral lobe of the cucullus is small. The sterigma in female genitalia can be similar to that in G. dealbana but the sclerite of the cingulum is much longer.
In Europe, this genus has one generation per year and hibernates as larvae or pupae. Adults emerge in June. The larvae feed in buds, leaves and twigs mainly of Salicaceae and Betulaceae (Razowski 2003). This genus also consists of leaf-rolling larvae that feed within their rolled leaves of Salix and Populus in North America (Miller 1987).

This genus has a primarily Holarctic range (Eastern Europe and Russia) with seven species recognized in North America (Arctic Canada to US) (Gilligan et al. 2008, Fernald 1882, Pohl et al. 2010, Kuznetsov and Mikkola 1991, Razowski 2003).
