The white hickory tussock moth caterpillar may look innocent enough, but it packs a powerful punch.
These poisonous caterpillars originate in Canada but are now found throughout the eastern half of the United States. They are usually white with a black band down the center of their back. The hairs that make the caterpillar appear cute and fuzzy are actually a way to protect it from predators. The hairs contain barbs that can embed in your skin.
The caterpillar also excretes a chemical upon contact that can cause an allergic skin reaction.
The result is red, itchy rash that will leave you miserable.
If you come across a white hickory tussock moth caterpillar, the best course of action is to simply give it a wide berth and avoid touching it. A white hickory rash can normally be treated with over-the-counter rash creams, but you should see a doctor if it persists.
The caterpillars are prevalent between June and September.
The female lays clumps of eggs that can number into the hundreds. They are found primarily around oak, aspen, willow, elm, and nut trees where they munch on the leaves. In the fall, they form webs and emerge in the spring as moths.
