Caterpillars can sting

Next on our caterpillar facts is their stinging abilities. Stinging caterpillars, like the Puss Caterpillar, Io Moth Caterpillar, and Flannel Moth Caterpillar, possess specialized structures with venomous spines or irritating substances as a defensive adaptation. Found in various regions of North and South America, these caterpillars deliver painful stings when touched, deterring predators and potential threats.

Contact with the venomous spines can cause localized reactions, such as an intense burning sensation, swelling, and redness.

While the stings can be uncomfortable and lead to allergic reactions in some cases, they are generally not life-threatening for humans and subside over time without medical intervention.

However, it is best to avoid handling or touching caterpillars in the wild, especially if unsure of their identification, and exercise caution when exploring natural habitats where other caterpillars may reside.
