The head is bluish-grey; the body is reddish-orange above, but greyish-blue on the sides; while the dorsal line is white, with a black edge. There is also a wavy orange line in the vicinity of the spiracles; and on several segments are a number of black spots. The whole insect is hairy. Apple-trees are chiefly attacked amongst cultivated fruits; but, in the shrubbery Hawthorns are frequently infested. The caterpillars live in a common nest, to which they return after feeding. In wet or dull weather they do not venture forth, and then is the cultivator's opportunity for getting rid of the pests, by cutting out the nest and dropping it into a pail containing an insecticide. Towards the end of the larval life the caterpillars separate, and assume the pupal state on or near the food-plants. The Moths are on the wing in late summer, the females depositing their eggs in rings (Fig. 702). The insects are yellow of some shade, and have trans- yiq. -02. Eggs of verse bands upon the fore-wings, varying Lackey Moth. from pale yellow to brown. Paris Green should be sprayed upon the trees, as the cater- pillars are leaf-feeders. In winter the characteristic rings of eggs should be searched for and cut off, as this will prevent the tree from being attacked in the following spring, when in the ordinary way such eggs would hatch out. Leather-Jackets {Tipiild).—An appropriate name for the tough larvae of certain Crane Flies, or Daddy Long-Legs (Fig. 703). The perfect insects are so well characterised that no de- scription is necessary. They are usually found skimming over lawns and gardens in autumn. The Leather - Jacket grubs are rather more than an inch long, and reddish, covered with tubercles, and with a black head. They are provided with biting jaws. The plants most attacked in the garden are the members of the Brassica Fig. 703.—Daddy Long-Legs.
