Which statement accurately describes adult mosquitoes?

Adult mosquitoes are characterized by having a defined head, thorax, and abdomen, which is typical of their classification as insects. Each of these three body regions serves distinct functions: the head contains sensory organs and mouthparts, the thorax is where the legs and wings are attached, enabling movement and flight, while the abdomen is primarily concerned with digestion and reproduction. This segmentation allows mosquitoes to perform vital actions necessary for their survival, including feeding and mating.

Other statements fail to accurately convey the structure of adult mosquitoes. There are distinct body regions, which means the claim that they have no body regions is incorrect. The thorax is not made up of independent segments but rather is one cohesive section that supports the legs and wings. Finally, adult mosquitoes always possess wings and legs, and an absence of these would classify them differently and not as typical adult mosquitoes. Understanding this structure is essential for recognizing their biology and behavior, important for effective pest management strategies.
