Medford, Jackson County, Oregon, USA July 2, 2008 Size: 10mm
Attracted to light. Quite common in western states. Adults can be found on pine, fir, spruce, and hemlock, are brownish-orange to dark brown, and may have an indistinct diagonal white line across their back (as can be seen here) which is a useful identifying trait. Coloration resembles bird droppings which helps protect it from predators.
