Pine Butterflies

OPB | Feb. 2, 2012 8:30 p.m.

An exceedingly rare population explosion of pine butterflies fills the Malheur National Forest with a virtual snowstorm in August. The mysterious outbreak may occur for 2 or 3 years and then disappear for 3 decades. The beauty extracts a price: the butterflies, while caterpillars, ate needles off 250,000 acres of trees.
