Beetle found on Potato plant-life cycle
May 30, 2010
We found this bug on a potato plant in south western Bulgaria. We have the entire life cycle from beginning to adult. Thought these would be interesting photos for you. Our Bulgarian friends said these insects come from Colorado but we don’t know what they are, maybe you can help. Feel free to post these pictures.

Dear Josh and Chantelle,
How wonderful it is that you have provided documentation of nearly the entire life cycle of the Colorado Potato Beetle, Leptinotarsa decemlineata, a species native to the mountains of Colorado. With the cultivation of potatoes, the Colorado Potato Beetle range has spread nearly everywhere potatoes are cultivated.
According to BugGuide: “Before the introduction of the potato in the US this beetle was confined to Colorado and neighboring states feeding on some native species of Solanum (night shade), now it has spread to most potato growing areas. It has been transported to Europe where it has become a serious pest.”
