An exception to this is the case of the antlered maple worm {Heterocampa gutivitta), which stripped thousands of acres of maple and beech along the mountain sides from central Maine southwest to the Adiron- dacks in the summers of 1908 and 1909. These caterpillars arc bright green with a saddle- shaped mark of purple, and when just hatched from the eggs have small, branched antlers just back of the head. The eggs of this family are laid on the foliage of the food plant, and the larvae descend to the ground to pupate, the pupae usually remaining in the soil over winter. The measuring-worms (family Geometridae) are the caterpillars of a large family ; they have but one or two pairs of abdominal prolegs, so that as the middle of the body is unsupported they are unable to walk like ordinary caterpillars, but loop along in a characteristic fashion, which has given them the com- mon name of " inch-worms " or " measuring ; Many of them will stand with the body stretched out stiff and motion- less, so that they are readily mistaken for broken twigs and are probably passed over by ,, , , , ,, , birds seeking food.
