The females deposit their eggs, which are small, oval, and black, on twigs and bark in the autumn; the insect is hatched out the next spring, and feeds upon the sap of the tree. The first broods are all females, which in a short time, without any intercourse with the males, give birth to living young by the process of gemmation. These also produce other young ones, which are all females as long as the summer lasts, and it is only in the autumn that males are produced, which, uniting with the females, become the parents of the eggs for the following spring brood, thus bearing living young all the summer, and laying eggs which can withstand the frosts of the winter in autumn for the following spring season, while the parent insects in winter are destroyed by the wet and cold weather and alternate freezing and thawing.
