scientific name    Chytolita petrealis    

common name     Lesser Luteous Snout

Mesic wooded areas, bogs and swampy areas.

Adults are on the wing in late May and June.

A small (2.2-3.0 cm. wingspan) delicate moth. The forewings are powdery light grey, crossed by a darker narrow antemedian and postmedian lines, the latter curving outward in a semicircle on the upper half. The subterminal line is a series of dark dots or small wedges, with pale scales on the outer edges. The reniform is a small patch of dark scales. The hindwings are similar, with faint antemedian and postmedian bands. The antennae lack the notch found before the slight tuft in Zanclognatha species, and have a large fan-like tuft on the foreleg tibia.

life history
Adults are nocturnal and come to light.

diet info
Prentice (1962) lists a single collection from Tamarack (Larix). However, this is an unusual record, as most Hermininae (as well as the closely related C. morbidalis) all feed on dead leaves, lichens or fungi.

From Nova Scotia and New York west across Canada to the interior of British Columbia, south to Montana, Virginia and Tennessee. Probably throughout most of Alberta. It has been collected from the Cypress Hills and Lethbridge, and north along the foothills and mountains to Jasper, and across the southern Boreal forest and Aspen Parklands regions.
