These beautifully patterned moths can be found across much of the US, except for the southwestern states. Since they are found across a wide range, the caterpillars are capable of feeding on many hardwood and softwood species of shrubs and trees including pine, hemlock, fir, larch spruce, alder, ash, birch, and more. While they may have more than one brood a year in other (warmer) parts of the country, there is only one generation here in MT.
Size: Wingspan is 19–25 mm
