It is native to the western United States. The larvae of the Pandora moth feed on the foliage of several species of pine trees, including the lodgepole, Jeffrey, and ponderosa pines. The larvae populations sometimes reach high enough levels to cause severe defoliation; such outbreaks have occurred in northern Arizona, central Oregon, and southern California. The Paiute people in California's Owens Valley and Mono Lake areas harvest, prepare, and store the larvae (which they call piuga) as a preferred food. This has brought the natives into conflict with the United States Forest Service, which has sought to control moth populations through the use of insecticides.
Pandora moths are semivoltine, producing one new generation every two years. Around the end of June, the adult moths appear; they lay eggs which hatch in August. Over the winter, the larvae remain on the tree, feeding on its foliage. The following summer, the insects drop off the trees and pupate, burying themselves in the ground, where they will...

Rare
Under 5% of wildlife watchers report a Pandora Pinemoth sighting in Portland on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 466th most-seen of the 507 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Pandora Pinemoth in Portland on a given day, so our monthly data shows no clear season.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Pandora Pinemoth sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Portland, in our data
Portland is the only city on Wallace's Line with enough records to rate Pandora Pinemoth sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Pandora Pinemoth is recorded against all the insects logged in Portland (5 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
