In case of the pea wee^•iI the eggs are laid out of doors on growing pea pods and they burrow into the pod and get into the growing peas, usually one to each ])ea. They grow with the growing pea and remain in the pea to pupate and then later the adults are found in stored peas in winter and spring. Immense numbers of these larvse are destroyed by the eaters of green peas but the species holds its own. It does not become noticeable except in stored peas. The Iar\fie at the time of green peas are small 13.
