Entry Last Edited: 04/12/2023 | Content ©www.BugsOfTennessee.com

Insect Order (Hemiptera)

Piercing and sucking mouthparts - or rostrum - are what differentiate True Bugs from the rest and this means that the insects generally fed on plants as a natural diet. Around 12,000 such species are recognized in North America alone. These bugs can be found on land and in the water and have thick wings kept close to the body. A prominent identification feature is the triangular-shaped scutellum located on the thorax aft of the protonum. The Hemiptera order covers True Bugs, Cicadas, Hoppers, and related insects.
