scientific name    Trachea delicata    

Wooded portions of the Grasslands region.

Adults have been collected in Alberta from early June through to the later half of August.

A medium-size moth (3.6-3.8 cm wingspan) dark brown moth. Forewings are dark brown, with the orbicular, reniform and claviform spots prominent and marked with black scales. The subterminal line is narrow and somewhat erratic, marked with a mixture of pale pink and black scales. The most prominent marking is the pale pink-brown oblique stripe running from a point between the orbicular and the reniform to the subterminal line near the anal angle. Hindwings are slightly paler brown than the forewings. Antennae are simple and the sexes are similar.

life history
The adults are nocturnal and come to light, and also to bait. The flight period is very long, and may indicate more than one generation per year.

An uncommon but widespread species, at the western edge of its range in southern Alberta.
