What Do Potato Bugs Eat?

Potato bugs are classified into two different categories:

  • The Jerusalem Cricket
  • The Colorado Potato Beetle

The Jerusalem Crickets or potato bugs (Stenopelmatus fuscus) are discovered in the western and southern regions of the United States. They are a group of wingless insects having large, human-like jaws, heads, and an alien-like appearance. Potato bugs are large and can be 2-3 inches in length. They also have amber yellow heads, legs, and thoraxes with black-brown rinds on the abdomen.

Colorado Potato Beetles (Leptinotarsa decemlineata) belong to the nightshade or Solanaceae family and are endemic to the United States except for Alaska, California, Hawaii, and Nevada. They barely reach an inch and have black vertical stripes with hard yellow-orange outer wings.

What Do Potato Bugs Eat?

Jerusalem crickets and Colorado potato beetles are called potato bugs due to their eating habits. The diet of Jerusalem cricket includes other insects, roots of vegetable crops, and of course their favorite potato tubers in the potato field.

On the other hand, Colorado potato beetles don’t just harm potato crops but other vegetables like tomatoes, peppers, and eggplants from the Nightshade family. Female potato beetles lay eggs underneath the foliage, and the larvae survive by eating the leaves.
