Pandora moth

53 host plants

You will see clusters of caterpillars with dark bodies and long spiny hairs feeding on pine needles in spring and early summer. Larvae are gregarious when young, becoming solitary as they mature. Damage appears as defoliated branch tips and browning needles. Adult moths emerge in mid-summer. Multiple pine species suffer damage including lodgepole pine and western white pine in Eastern Washington and mountain regions.

Pandora moth occasionally reaches outbreak levels in forest settings but rarely causes landscape damage. Monitor for defoliation on small planted pines. Hand-remove larval clusters when present. No chemical treatment is typically warranted. Prune severely defoliated branches. Natural parasites help control outbreaks.
