General Description
provided by University of Alberta Museums
A small (2.0-2.6 cm wingspan) narrow-winged moth with dull reddish or brownish-grey forewings and paler hindwings. The forewings have a prominent, dark oblique median band that stops well before the costa, and a dark, bar-shaped reniform. The antemedian and postmedian lines are fine, and the later is curved. There is a yellow or orange patch on the outer margin below the apex, and a dark terminal line and grey fringe. The hindwings are pale, crossed by fine median and submedian bands, and darkening toward the margin and in particular in the region just before the anal angle. The palps are massive, in the male folded back up and over the head and thorax, and containing a large expansible yellowish tuft. The antennae are simple and both of the sexes are similar.

Trophic Strategy
provided by University of Alberta Museums
No Alberta data available. Elsewhere in Canada, recorded from a wide variety of trees and shrubs, but mainly confer trees, in particular Balsam fir (Abies balsamifera) and White spruce (Picea glauca). See Prentice, 1962 or Handfield, 1999 for lists of recorded hosts.

provided by wikipedia EN
Palthis angulalis, the dark-spotted palthis, is a moth of the family Erebidae. The species was first described by Jacob Hübner in 1796. It is found from Newfoundland west to coastal British Columbia, south to Florida and Texas.
The wingspan is 20–26 mm. Adults are on wing from May to August in Alberta. There are two generations in much of the eastern part of its range, three or more generations from Missouri southward.
The larvae feed on various plants, including forbs, woody shrubs and trees (alder, aster, basswood, birch, chestnut, fir, sweetgale, goldenrod, ninebark, rhododendron, scrub oak and spruce).
