Larva Aka: wrigglers Lives in water 7-14 days Breath through siphon (tube) During growth, skin sheds 4 times 4th molt, next stage inch long Some species just lie parallel to the
waterSource: http://mosquitoes.org/LifeCycle.htmlImage by Jonathan
Pupa Aka: Tumblers 1-4 day life cycle Float on surface 2 Breathing tubes called Trumpets Doesn’t eat “Burst Open” into adult

Adult Aka: Imago Males feed on nectar of plants Females need a “blood feast” to lay
eggs After feeding, they will rest, 3 days to

Mortality Rate in Stages Egg rarely die
live for 1 day look like algae
Larva highest mortality rate High starting population very small changes could suffocate.
Pupa also rarely die lasts a couple days don’t even need to eat
Adult second highest mortality rate females are often targeted few can identify a male Source:
