A mosquito is a small flying insect known for its ability to bite and suck blood from animals and humans. They have long, thin bodies and delicate wings, making them agile fliers. Mosquitoes are most active during warm weather and are often found near standing water, where they lay their eggs. These insects are not just annoying; they can also spread diseases like malaria, dengue fever, and Zika virus. Female mosquitoes require blood to develop their eggs, while males primarily feed on nectar. Understanding mosquitoes is important for preventing their bites and the diseases they can transmit.
