DaBrAt37Colorado Potato Beetle, medium-sized beetle, member of the leaf beetle family, serious threat to potato crops. Colorado potato beetles are native to the eastern Rocky Mountain region of the United States. Before potatoes were widely cultivated in North America, these beetles fed on food plants belonging to the nightshade family. When potatoes began to be cultivated in the United States in the mid-19th century, the beetles were provided a vast new food supply, since the potato plant is a member of the nightshade family. The Colorado potato beetle rapidly infested the potato-growing regions of North America. It was accidentally introduced into Europe in 1922, but its spread has been slowed by rigorous extermination efforts.
Both larvae and adult beetles feed on potato foliage, though they sometimes also consume vegetables and flowering plants. The Colorado potato beetle typically lays bright yellow eggs in clusters on the underside of leaves. Several generations of the insect can reproduce in a single year. .
Scientific classification: The Colorado potato beetle is a member of the family Chrysomelidae. It is classified as Leptinotarsa decemlineata.
