ELI5 What do mosquitos do during they day?

First of all, any individual adult mosquito only lives for about a week.  During this time, mosquitoes will eat (fruits, nectar, other sweet substances), rest, and find mates.  

Female mosquitoes will also find hosts from which to gather blood.  They need the blood of animals to help with egg production as the blood is rich with proteins.  The process by which the proteins in the blood are broken down and then reformed into eggs can take two to three days, depending on species and habitat conditions.

Like many flies, mosquitoes lay their eggs in water; in doing so, the female will dip her ovipositor into the water over and over and create a "raft" of eggs.  Eggs hatch into larvae in as little as 48 hours and become adult mosquitoes in one to two weeks.

Did you have any other specific questions about mosquito behavior?
