General Description

المقدمة من University of Alberta Museums
A medium size moth (approx. 3.5-4.0 cm wingspan). There are two forms, one a light grey with a purple or pink tint, the other dark purple-grey. Markings consist of doubled dentate antemedian and postmedian lines, often faint or difficult to trace except for a black spot or bar where they meet the costa. The large round orbicular and the reniform spot are filled with slightly paler scales. The area in the cell basad to the orbicular and the lower part between the orbicular and reniform is black. The rest of the area between the reniform and orbicular is partially filled with reddish brown scales and the area beyond the postmedian line is also mixed with reddish-brown, although these may not be obvious. Pale forms are quite powdery and contrasting, while dark specimens appear quite even and smooth. Sexes similar, but males with bipectinate antennae, females with simple antennae.

Xestia praevia ( الإنجليزية )

المقدمة من wikipedia EN

Xestia praevia is a moth of the family Noctuidae. It is found in Canada (New Brunswick, Quebec, Manitoba, Saskatchewan, Alberta and British Columbia) south to California. It is part of the elimata species group. Three of the species in this group (Xestia praevia, Xestia elimata and Xestia badicollis) have no significant difference in both genitals and DNA, suggesting they may be in fact one species.

This wingspan is about 32 mm. The moth flies from July to August depending on the location.

The larva feeds on Pinus ponderosa.
