The brown caterpillar, commonly known as a browntail moth, has a brown body with white streaking, orange dots, and irritating hairs that cause similar rash and breathing problems to poison ivy.
The caterpillars feed on oak, apple, cherry, and pear trees. They are found in the eastern parts of the United States and Canada. While most caterpillars do not bite or sting, the caterpillar’s hairs can cause skin rashes or hives. Those affected may also experience difficulty breathing as a result of the toxin from the caterpillar. The toxin from the caterpillar is known as ‘Toxicodendron,’ which means ‘poisonous tree.’
The symptoms from contact with the browntail moth usually appear within minutes of exposure but may take up to 24 hours to develop. Children are at greater risk for reacting to exposure than adults because of their smaller size and more sensitive skin. It is important to note that those affected by this insect will not have an allergic reaction upon subsequent exposures but rather a worsening of previous symptoms upon repeated exposure.
