Diagram of a typical insect leg The typical and usual segments of the insect leg are divided into the coxa, one trochanter , the femur, the tibia, the tarsus, and the pretarsus .

The white egg at first is elliptical (1.5 mm by 2.1 mm) but becomes more spherical as the larva inside develops. These hatch into white grubs about 18 days after laying. The newly hatched larvae are 8 mm long and grow to a length around 40 mm. Whitish with a brownish-black head, the grubs have conspicuous brown spiracles along the sides of ...
