It’s National Moth Week again, so we sketched moths (and their larvae) on Draw With Me.

Halysidota tessellaris, the banded tussock moth, is found in North America from southern Canada south through Texas and central Florida. Adult moths are attracted to decaying plants with pyrrolizidine alkaloids. They regurgitate on them, then drink the fluids, and thus acquire defensive chemicals that offer protection from predators.

Megalopyge crispata, the black-waved flannel moth, is found along the east coast of the United States, and as far inland as Oklahoma. The caterpillars produce a venom, delivered through hollow hairs that penetrate the skin, that can cause pain, headache, inflamed lymph glands and dermatitis. They may look cute and furry, but don’t go petting them!
