Abstract
The life history of any insect if carefully and conscientiously traced, will show many and striking adaptations. These in the aggregate will be found to display a marvelous adjustment to and harmony with the environment. The life cycle may be long or short, occurring early or late, the generation one or more and the winter passed as egg, nymph or adult, according as these variations adapt the insect to its individual niche in the scheme of things.
