The evolution of the name Colorado potato beetle is curious because the beetle is believed to have originated in central Mexico, not Colorado. It had a series of names from 1863 to 1867, including the ten-striped spearman, ten-lined potato beetle potato-bug, and new potato bug. Colorado was not associated with the insect until Walsh (1865) stated that two of his colleagues had seen large numbers of the insect in the territory of Colorado feeding on buffalo-bur.
The life cycle of the Colorado potato beetle starts with the adult as the overwintering stage and can be as short as 30 days. Adults dig into the soil to a depth of several inches and emerge in the spring. They feed on newly sprouted host plants where they mate. Larvae drop from the plants and burrow into the soil where they construct a spherical cell and transform into yellowish pupae. This lasts from five to 10 days. There are one to three generations per year, depending on latitude; however two generations can occur even as far north as Canada.
Potatoes are the preferred host for the Colorado potato beetle, but it may feed and survive on a number of other plants in the family Solanaceae, including belladonna, common nightshade, eggplant, ground cherry, henbane, horse-nettle, pepper (rarely), tobacco, thorn apple, tomato, and, its first recorded host plant, buffalo-bur.
