The larva (Figs. 162, 163) on hatching from the egg digs a burrow in the position of the ovipositor hole. The eggs, which are laid in June, hatch in two weeks and the larvae live in the spot where the eggs were laid for one year, and transform into pupae (Fig. 164) in the ground in an especially prepared cavity (Fig. 165). The adult, which is a reddish-.
