Central Oregon is at the tail end of a Pandora moth outbreak, which typically last three or four cycles of two years. These moths are native to the region and have a two-year life cycle. During the first year of these moths’ lives they can be found in forests as larvae that look similar to a caterpillar, where they consume pine needles.
This summer is the second year of the moths life-cycle, meaning the larvae have turned into the large, two to five-inch moths that are found all over Central Oregon. This is the third-generation of this outbreaks larvae-moth cycle, meaning we may see them again in two years or they may go dormant again.
