This time of year, many caterpillars are actively feeding on trees throughout the state. These spikey little caterpillars will turn into the IO moth, a species common throughout South Carolina. Adults are either yellow or brown with large dark “eye spots” on the hindwings. Larvae feed on many different hardwood tree species, including oak, birch, hickory, and dogwood. These larvae were found on a swamp white oak. Keep in mind that any caterpillars with hairs or spines may sting you if touched, so please don’t touch them unless it’s absolutely necessary. For more information, see HGIC 2482, Stinging Caterpillars.
