Your caterpillars are Cinnabar Moth Caterpillars, Tyria jacobaeae, a species, that according to BugGuide, was “Introduced from Europe as a control for introduced weedy Ragwort, the host plant for its caterpillars, which is toxic to livestock.” The Cinnabar Moth is now well established in Oregon and Washington.
