Western United States
Pine forests
Adults fly from July to September
Larvae feed on the leaves ("needles") of various species of pine (Pinus). Particular host records include: Ponderosa pine (Pinus ponderosa), Jeffrey pine (P. jeffreyi), lodgepole pine (P. contorta), sugar pine (P. lambertiana), pinyon pine (P. edulis), and Coulter pine (P. coulteri).
Adults do not feed.
Life Cycle
Two years are required to complete development. Second- or third-stage caterpillars overwinter the first year in tight clusters, resume feeding in the spring, pupate in June or July, and spend the second winter in underground pupation chambers lined with silk and plant litter. Some can remain in the pupal stage for up to 5 years before emerging as adults.
[copied from text at]
Larvae are prepared and eaten by Paiute natives in California. For more info, see the brief account at Wikipedia, or more detailed journal articles like Aboriginal Exploitation of Pandora Moth Larvae in East-Central California or Harvesting Pandora Moth Larvae with the Owens Valley Paiute.
