PUSS CATERPILLAR (Megalopyge opercularis) - ©Caterpillar hunter
The Puss Caterpillar, or woolly slug, is the most poisonous caterpillar in the United States. It spits acid on predators. The fur of the larva contains venomous spines that cause extremely painful reactions in human skin upon contact. It has numerous common names, including Southern Flannel Moth, Pussy Moth, Puss Caterpillar, Bolivia Bug, and Asp in Texas. It is visually striking in both larval and adult forms. The resemblance of the larvae to soft, colorful cotton balls encourages people to pick them up and pet them. It can be found on oaks, elms, citrus and other trees, and many garden plants such as roses and ivy.
