Observation notes: Unsure of identification. Its head was orange; its body looked like a soft furry pinecone, the way the hairs folded. The protruding hairs looked like a mix of a rust color and gray. Was seen with a different species of caterpillar/moth, along with another of its own kind on the same plant--I believe common milkweed. Nearby plants included butterfly bushes, zinnias, larkspur, a lupine, and sunflowers. Size: Approx. 1.25" Weather: Hot, humid and windy.
