The Jewel-tailed Slug Moth has a cluster of white dots reminiscent of a strand of pearls on its wings.
Most individual Jewel-tailed Slug Moths are light brown with a dark brown inner patch on the forewings. Some are medium brown with a very dark patch that better highlights the white dots on them. At the inner, bottom edge of the forewings, sits a trio of white spots though one of the spots may be hardly visible. The center spot is larger than the others, much like a necklace showcases the largest gem in the middle of the strand.
The caterpillar of this moth looks like a slug and lacks the typical worm-like shape seen in most moths and butterflies. This larva's green body is wide and oval-shaped with a raised ridge on the center of the back. A 'tail' extends from the rear end. It feeds on trees like birch, hickory, oak, and spruce.

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
