Pandora moth returns to Central Oregon

What is causing recent defoliation of pines in forest areas to the west and south of Bend?

This defoliation is caused by the Pandora moth, Coloradia pandora (Lepidoptera: Saturniidae), which is a native defoliator of pine forests in the western United States. Outbreaks have occurred commonly in central Oregon.

Haner Park, Wild River, and the non-commercial thinning units adjacent to Ponderosa Pines: Small tree thinning and piling completed by November 2017, pile burning and brush mowing to follow. Thinning remaining units near Ponderosa Pines will likely begin in 2018.
