Black Spikey Caterpillar
Dear What’s That Bug,
My son and I found this black spikey caterpillar in the backyard eating some cottonwood leaves. It is mostly black with a lot of tiny white dots, tiny white hairs, and long black spikes all over its body. It also has five pairs of orange feet and rust colored spots down the middle of its back. We think it looks similar to a mourning cloak caterpillar that we saw on your site. Is that what it is? Thank you
You are correct in your identification of this Mourning Cloak Caterpillar..
