Orangestriped Oakworm (Anisota senatoria) - Orange-striped oakworm caterpillars are distinctive and relatively easy to identify. Young caterpillars are greenish yellow with eight orange stripes that run the length of their bodies. As the caterpillars grow, they become black and the orange stripes become more evident. The caterpillars have two characteristic black, hornlike projections just behind the head. Caterpillars rapidly increase in size and may grow to 3 inches in length by the time they finish feeding. Adult moths have bright orange-yellow bodies. The forewing has many dark spots and a single, distinct white spot near the long edge.
