Northern Corn Rootworm
A pale green beetle whose larvae attack corn root systems. It can survive crop rotation by extending egg diapause for two years.
Did You Know?
Its eggs can remain dormant in soil for over two years, defeating traditional crop rotation strategies.
South American Tortoise Beetle
A moderately large tortoise beetle with a distinctive pattern of dark markings on a lighter background, with broadly expanded elytral margins. Found in tropical South American forests.
Did You Know?
The broadly expanded margins of its shell-like body can be pressed flat against a leaf surface, creating a sealed edge that is nearly impossible for predators to breach.
