What is a key difference between male and female mosquitoes?

The key difference between male and female mosquitoes lies in their feeding behaviors, particularly regarding blood consumption. Female mosquitoes require the proteins and nutrients found in blood to develop their eggs, which is why only females are known to suck blood. In contrast, male mosquitoes primarily feed on nectar and similar plant-based sources for energy and do not engage in blood feeding at all.

While it might be noted that other choices mention aspects related to size or egg-laying, these characteristics are either inaccurate or applicable to females. Males are generally smaller than females, and egg-laying is a function exclusive to female mosquitoes. Understanding these biological and behavioral differences is essential for effective mosquito control and management strategies.
