Edwards this species is devastating the pine forests in Mendocino County, California, and is particularly destructive to the Big Tree (Sequoia aentperrirenn), Pinna jmnderosvx, and Pinnx Inmhertiana. The eggs are laid in the axils of the branches, the young caterpillar boring in a tortuous manner about its retreat, thus diverting the flow of sap and causing large resinous nodules to form at the place of its workings. These nodules gradually harden, the branch then dies, and the tree at last succumbs to its insignificant enemies. Hundreds of fine trees in the forests of the region are to be seen in various stages of decay. The moths make their appearance in June and July, during which period the eggs are deposited.
