Time of Infestation May to August
Colorado Potato Beetle

Both the larvae and the adult beetles feed on the leaves of the plants. The larger the larvae are, the more they eat within a short time. They skeletonize the leaves and even eat whole fields bare if heavily infested. This prevents the bulbs of the plants from developing.

The Colorado potato beetle hibernates in the soil and begins maturation feeding on the potato leaves at the beginning of May for about two weeks. Then the females deposit countless clutches of yellow-orange eggs on the undersides of the leaves, from which the larvae hatch after 3 to 12 days. The larvae start feeding and pupate after four weeks or three larval stages in the soil. Already after another two weeks (approx. beginning of July) the beetles hatch and hibernate after maturation feeding in the ground from August on.
