Leptinotarsa decemlineata, commonly known as the Colorado potato beetle, is a small beetle native to North America. It is recognized by its distinct yellow-orange body with ten black stripes on its elytra (wing covers). This species is notorious for its role as a major pest in agriculture, particularly affecting potato crops. The beetle thrives in temperate climates and has a life cycle that includes egg, larval, pupal, and adult stages. Its adaptability and resistance to pesticides make it a challenging pest to manage.

Leptinotarsa decemlineata, commonly known as the Colorado potato beetle, is native to North America. Specifically, its original range included the region around the Rocky Mountains in the United States, particularly in Colorado, which is how it derived its common name.

The Colorado potato beetle thrives in temperate climates with moderate humidity and temperatures ranging from 15°C to 35°C (59°F to 95°F). It typically inhabits areas where its primary host plants, such as potatoes, eggplants, and other solanaceous crops, are cultivated. The beetle's habitat includes agricultural fields, gardens, and areas with wild solanaceous plants.

As a phytophagous insect, the Colorado potato beetle plays a significant role in agricultural ecosystems by feeding on solanaceous plants. It has adapted to survive in environments where these plants are abundant, and it is known for its ability to develop resistance to pesticides, which makes it a persistent pest in its ecological niche. Its lifecycle is closely tied to the availability of host plants, and it is known to overwinter in the soil, emerging in the spring to begin feeding and reproducing.
