Observation date: August 17, 2013
Submitted by: snowcat
Specimen type: Photograph
Observation notes: The fireweed was denuded in large swathes, all crawling with these prolific caterpillars. They jumped at the vibrations of my camera, and were more active than any others I saw on this day-too-cold-for-butterflies. This one, on a valerian leaf, was easier to photograph.
