Could this be a silver spotted tiger moth caterpillar? I’ve read they are poisonous but the Boy Scout leader said this one wasn’t. It was found near Guerneville, CA. There were coastal redwoods, Douglas firs and Bay Laurels in the area.
We agree that this might be the Caterpillar of a Silver Spotted Tiger Moth, Lophocampa argentata, based on this and other BugGuide images. According to BugGuide: “Note of Caution: Like several kinds of wooly-bear-type caterpillars, these have venomous, stinging hairs, which can cause a burning sensation and/or a rash in sensitive people- look, but don’t touch!” We believe the key words are “sensitive people” meaning most folks, including tough, young children, are not affected.
