Leptinotarsa decemlineataUrbana, IllinoisMeet the Colorado Potato Beetle. Anyone with a potato patch will recognize this large, pin-striped beetle as a particularly voracious consumer of potato leaves. When European settlers pushed west in the 1840's with their newly-planted potato fields, a world of culinary possibilities opened up for this native beetle. The colorado potato beetle evolves in other ways, too. No problem- thanks to a prolific life cycle and indiscriminate pesticide application, this beetle can now detoxify all of them.
