Which order includes true bugs and bedbugs?

The correct answer is Hemiptera, which is the order that includes true bugs, such as bedbugs, aphids, and various other insects with piercing-sucking mouthparts. Members of this order are characterized by having two pairs of wings, with the front pair typically being hardened and the back pair membranous. The term "true bugs" refers to the suborder Heteroptera within Hemiptera, which encompasses a diverse range of insects that share similar life cycles and ecological roles.

Bedbugs, specifically Cimex lectularius, fall under this classification due to their feeding habits and physiological characteristics. They possess specialized mouthparts that allow them to pierce the skin and consume blood, which is a defining feature of Hemiptera. Understanding the taxonomy of these insects is critical for pest control, as different orders can have vastly different behaviors and control measures.
