The wings of the Faint-spotted Palthis flare out and fold up while resting, adding dimension to its profile.
The strong, triangular shape of the Faint-spotted Palthis is often seen in Litter Moths. A narrow head and flared out wings share a similar look to some jet fighters. The profile of this species is also interesting. The middle of the wing curls up just enough to create a ridge, like a crease in a folding umbrella, that is best seen from the side view. The body of the moth is strongly arched, giving it a humpback. In addition to all of these features, the pattern on the moth is also useful for identifying it. Because individuals can range from light brown and taupe to dark brown with purple tones, the black patch at the top of the crease on each wing helps distinguish it from others in the same genus. A second black mark on the lower half of the wing has a thin, curved tan line crossing it. A wide dark band stretches between the tops of the wing creases, and dark patches along the bottom edge flank them. Hairy legs are often held in front of the face, extending its perceived length.
The caterpillars of the Faint-spotted Palthis feed on all sorts of plant leaves. Crops like corn and beans, flowering plants like coralberry and Spanish needle, and oak trees are all food sources. The dark brown caterpillar has light diagonal stripes that accentuate the segment bumps, and the rear end is flattened and raised, like a ramp. One or two broods are produced each year.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Butterfly and Moth Anatomy
Antennae: Butterflies and Moths have a pair of antennae on the head used as sensors.
Head: The head is home to the insect's eyes, antennae, and proboscis.
Thorax: Home to the three pairs of legs as well as vital internal organs.
Abdomen: Contains vital internal organs such as the heart(s) and reproduction facilities.
Forewing: The upper, forward wing pair used for flying.
Hindwing: The lower, rearward wing pair used for flying.
NOTE: Butterflies and Moths are part of the Lepidopteran order as they share many similarities.
