. Bulletin - New York State Museum. Science. Fig. 22 Forest tent-caterpillar: a cluster of eggs; b female; c top ^ew of an egg; d side view of several eggs (after Riley) 30 Forest tent-caterpillar: maple worm (Clisiocampa dis- stria). Foliage of maple and fruit trees eaten in May and June by hairy blue headed caterpillars with silvery dots along the back. The cocoons are spun in June, the brown moth, with darker oblique bands across the wings, flying in July. Eggs in belts in- circling smaller twigs are covered with a light brown protective substance, and remain unhatched till spring. Treatment: remove and destroy the eggs; kill the caterpillars when massed on trunk and limbs, either by crushing or by spray- ing them with kerosene emulsion or with whale oil soap solution; spray the foliage of infested trees with poison; collect and destroy the cocoons. 31 Pigeon Tremex (Tremex columba). The large, four winged, brownish adults marked with yellow, frequently known as " horn tails ", are usu- ally found in July around diseased and dying tree trunks. The eggs are de- posited a short distance within the bark, and the young borers occur near the surface, but full grown ones may make their way to the center of even large trees. This insect is not usually very injurious. Treatment: cut ^nd burn badly infested trees. 32 lunate long sting (Thalessa lunator). A magnifi- cent brownish, wasp-like insect, with yellow markings and a.
