Painted Tiger Moths are part of a bold and attractive, and somewhat large, moth family. This species is no exception. The dense marbled pattern on its forewings makes a great cover for the bright, rosy hindwings that are visible when the moth is resting with wings spread or in flight. The Painted Tiger Moth is at home in the North American southwest and can be seen in arid chaparral as well as open fields.
Eggs are shiny and oblong shaped. Larvae hatch in the spring and nibble at the foliage of low-growing plants. Caterpillars are black with blots of rusty-orange on the body where tufts of bristles grow. They are mostly active at night, when their natural coloring offers camouflage. Adults do not eat. They emerge in the summer and are active all season long as well as into the fall.

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.
