Commentary

Dear Craig, this is likely the western tent caterpillar, a native moth. If you are interested in management, the caterpillar can defoliate your tree, cut the nest with the caterpillars off and dispose it off. Thank you for contacting our Invasive Hotline. Best regards, Helmuth Rogg, Oregon Department of Agriculture
