Colorado beetle

Leptinotarsa decemlineata

About 10 millimetres long, the Colorado beetle is easy to identify by its yellow thorax, and its striped black and yellow wing cases with 10 black lines. The antennae and legs are dark, and it has an oval body.

The Colorado beetle lives in potato plantations and originates from the Rocky Mountains. It was introduced into Europe gradually during the past two centuries and can now also be found in Asia.

Both the adults and larvae feed on potato leaves. The female lays 20 to 80 eggs that adhere to the lower part of the leaves. The larvae are rose-orange with black spots. The beetle causes severe damage to potato crops.
