JulJ, CATERPILLARS INJURING FOLIAGE. 215 die of the back runs a black stripe, and on either side of the bodyare tiiree stripes of black alternating with four of yellow, thebody being thinly clothed with long, soft, white hairs. The cat-erpillars feed together in colonies and are often found clusteredtogether on a limb in a solid mass. If the limb bearing it isjarred or if a caterpillar is touched, it at once assumes a positioncharacteristic of this genus, throwing the head and tail in theair with a jerk and clinging to the limb by the abdominal prolegsas shown in figure 6, a. A caterpillar will remain in this appar-ently lifeless position for several minutes, being the most accom-modating insect to pose for a photograph we have met. Pupa.—The full grown caterpillars descend from the tree atnight and burrow into the earth for from two to four inches andther
