scientific name    Gypsonoma salicicolana    

Inhabit boreal forests with occasional occurrence in small patches of grassland in boreal regions (Pohl et al. 2010).

Adult flight periods occur from June to early July and specifically July to August in Alberta (Gilligan et al. 2008, 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 10-11mm (with their forewings 4.5-5.5mm in length) (Heinrich 1923, Miller 1987, Gilligan et al. 2008). The forewings have dark areas and markings that are grayish brown in coloration. The forewings can vary in color from light brown to graish brown. The hindwings are paler than the forewings. This moth can be distinguished from other moths of this genus by its size. It is the smallest midwestern moth of its genus. The basal patch does not differ much in color from the interfacial area adjacent to it. Some specimens in Iowa have a metallic blue cast on the interfascial areas (Gilligan et al. 2008).

life history
In North America, this genus consists of leaf-rolling larvae that feed within their rolled leaves of Salix (Miller 1987). These larvae then pupate (mostly likely hibernate as larvae or pupae) and emerge from their leaf rolls as adults in July (Razowski 2003). Most likely multiple generations per year at lower latitudes.

No information available.

diet info
The larva is a leaf-roller and feeds on Salix (willow) (Prentice 1966). They can also be inquilin feeders in falls on Salix (Heinrich 1923, Fernald 1882).

This genus has a primarily Holarctic range with seven species recognized in North America (New Hampshire to Manitoba and south to Florida and Louisiana) (Gilligan et al. 2008, Fernald 1882, Pohl et al. 2010).

Also referred to as Gypsonoma saliciana.
