In 5 to 10 days, the adult beetle emerges to feed and mate. Eggs are laid in clusters and are a bright orange in coloration.  Other forms of pest control, through nonpesticidal management are available. After World War II, in the Soviet occupation zone of Germany, almost half of all potato fields were infested by the beetle by 1950.

The mechanisms used include improved metabolism of the chemicals, reduced sensitivity of target sites, less penetration and greater excretion of the pesticides, and some changes in the behavior of the beetles. Adults have black heads with orange marks, round vibrant orange and/or yellow exoskeletons, and ten black stripes. However, many chemicals are often unsuccessful when used against this pest because of the beetle's ability to rapidly develop insecticide resistance.
