While in the field looking for egg masses, DNR staff will also survey for the Asian longhorned beetle, a destructive wood and wood products pest recently found in wood-crated shipments from Asia. Gypsy moth is gradually moving into the northern counties of Indiana from Michigan. Once established, gypsy moth caterpillars can feed on a wide range of hosts, with oaks being their favorite food.
