What type of caterpillar is brown with small blue dots?
A yellowish-brown to brown caterpillar with small blue dots is a Spicebush Swallowtail. They form a shelter by joining two ends of a leaf together with their silk. As the leaves dry, they contract and the silk pulls the ends together, forming a capsule. Spicebush Swallowtails are commonly found near spicebush, honeysuckle, and mimosa.
