Young larvae feed gregariously, later scattering to feed. Host trees include walnut, hickory, butternut, apple, basswood, birch, elm, black locust, aspen and linden. Silverspotted Tiger Moth Adults emerge in July and August and deposit eggs on needles or twigs of coniferous trees. Larvae feed on Douglas fir, true fir, pine and other conifers. They spin cocoons of silk and body hairs, attaching them to twigs, needles, tree trunks or litter on the forest floor.
Stings can be rather painful.
This insect is similar in habits to the hagmoth. It overwinters in a cocoon on the ground. Larvae feed on the underside of rose leaves and other low-growing shrubs. Treatment for Caterpillar Stings Diagnosis is usually simple since a rash generally breaks out where the hairs or spines have made skin contact. Immediate application and repeated stripping with adhesive or transparent tape over the sting site may be helpful in removing broken hairs or spines.
