Crane Fly or Daddy-longlegs.

T. oleracea, the grubs or "leather jackets," so injurious to the market gardener, are its larva;. They attack the roots of scarlet beans, lettuces, dahlias, potatoes, etc, from May to August. During the last month and September they become pupae. Mr. Curtis observes, that - "It is said that lime water will not kill them, and suggests that if quicklime was scattered on the ground at night, it would destroy them when they come to the surface to feed; and all the gnats that are found on the walls, palings, ground or elsewhere, should be killed, especially the female, which would prevent any eggs being deposited in the ground. A mixture of lime and gas water distributed by a watering pot over grass, has completely exterminated the larvae, where they had been exceedingly destructive, and by sweeping the grass with a bag-net, like an angler's landing net, only covered with canvas, immense numbers of the gnats might be taken and destroyed." - Gard.
