Mosquitoes Quiz – Small Insect, Big Impact

Mosquitoes are small flies found almost everywhere except Antarctica and a few places like Iceland. There are over 3,500 species, but only some bite humans, and only females drink blood, which they need to produce eggs.

Mosquitoes spread diseases such as malaria, dengue, Zika, yellow fever and West Nile virus, making them the deadliest animals to humans. Ronald Ross proved the link between mosquitoes and malaria in 1897, transforming public health.

Bed nets, removing standing water, vaccines and new tools like Wolbachia bacteria help reduce disease. Mosquitoes also play roles in nature as food for fish, birds and bats, and some pollinate plants.
