The white flannel moth caterpillar feels like anything but flannel – it's prickly. Look closely, and you'll see long hairs extending from its sides. Clumps of shorter, stinging spines line its back and sides. The adult moth is white, as the name suggests, but this larva wears a color scheme of black, yellow, and orange.
