The name for the Long-horned Slug Moth stems from its caterpillar's long antennae at the head that are double the size of the protrusions at its rear.
Not much is known about the life history of this species. The Long-horned Slug Moth adult is a light tan color with furry tan legs. Thin white lines curve across the wings with brown spots following their curvatures.
The larval form of this moth gets more attention. As a member of the Slug Moth family, the caterpillar looks more like a snail without its shell than a typical worm-like caterpillar. Its fleshy green body is oblong in shape and has groups of short bristles on it. The dorsal (back) side has a wide yellow-orange band that runs the length of the 'spine'. Two reddish-purple diamonds are linked to each other near the head with three more reddish-purple diamonds near the rear. A gap between these front and rear sets resembles a break in the diamond chain. Two long antennae extend from the head and two short nubby tails protrude from the rear. Both are red in color and covered in short hairs.

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.
