We saw this guy today (May 1, 2011) at a park in Los Altos California. The pic was taken about 7:30pm and it was about 75 degrees F. It was crawling on an artificial rock play climbing structure on the playground. Can you help us identify it?

Your Western Tussock Moth Caterpillar, Orgyia vetusta, shares many similar characteristics with its close relatives in the genus. BugGuide only reports this species from California, though its relatives including the White Marked Tussock Moth, Orgyia leucostigma, are found throughout North America. You should handle the Western Tussock Moth Caterpillar and its relatives with caution because BugGuide notes: “Contact with hairs may cause an allergic reaction.”
