Spotted Stem Borer

A straw-colored moth whose larvae bore into stems of maize and sorghum in Africa and Asia. It can cause total crop failure in heavily infested fields.

Did You Know?

The push-pull pest management system, using Desmodium and Napier grass, was developed primarily to combat this borer.

Yucca Giant-Skipper

One of North America's largest skippers with dark wings spotted in yellow-orange. Its massive caterpillar bores into yucca roots and stems, creating a silk-lined tunnel.
