(Malcosoma americanum) is the suspected cause of mare reproductive loss syndrome. Eggs overwinter on branches in large egg masses and hatch to form larvae that live as social insects in 'tents' from which they emerge to feed on leaves until approximately 2 inches in 4 to 6 weeks, after which they pupate to form a moth. Larvae (caterpillars) are hairy and black with a white stripe on the back and yellow stripes on the sides. Moths are red/brown with two diagonal stripes on each wing.
