The Colorado potato beetle (Leptinotarsa decemlineata), also known as the "striped weevil", is a major insect pest of potato and eggplant crops. Here is some information about its description and biology:

Description: The adult beetle is about 1 cm long and orange-yellow with black stripes on the elytra. The larvae are orange-red and about 1.5 cm long.

Biology: Adults emerge from the soil in the spring and feed on the leaves and stems of potato, eggplant and other nightshade plants. The females lay eggs in clusters on the lower leaves of plants, and the larvae hatch and feed on the leaves. The larvae go through several stages of development before turning into adults. The adults reproduce throughout the summer and the eggs laid by the last adults hatch in the fall, giving rise to adults which will overwinter in the ground.

Colorado potato beetles are considered garden pests because they can cause significant damage to potato and eggplant crops, reducing crop yield and quality. Infested potato plants may also be more susceptible to other diseases and insects.
