Seasonalitylate June IdentificationA medium-size moth (approx. 3.7 cm wingspan) with straw yellow forewings tinted with orange or pink to varying degrees. The forewings often have slightly darker shading under the basal half of the median line, and there is a small white spot at the end of the cell. The postmedian line is usually indicated by a few small dots at the veins. The hindwings are white with a light tint of the forewing color. The antennae are filiform and the sexes are alike. The pink form of L. anteoclara "calgariana" may be superficially indistinguishable, and the genitalia must be examined for a positive identification. The single large spine of anteoclara is located on a much longer diverticulum that also has a small "ear". This diverticulum is essentially lacking in farcta, and the spine is oriented back toward the base. Other Alberta Leucania have more strongly marked forewings and/or dark hindwings.

The adults are nocturnal and come to light. There is a single annual brood. The larval hosts of most Leucania, and probably also farcta, are grasses. Like most Leucania, farcta frequents meadows and other open grassy habitats. The lone Alberta specimen was collected in late June.
Diet Info The larval hosts are grasses. Range A western moth, common throughout much of BC and southward; north to the southern Yukon. Thus far known in Alberta only from a recent (2006) specimen collected near Jasper by Chris Schmidt and myself.
