Normally to prepare the larva for observation one would cut just arround the 7th section of the abdomen and then twist it to the side. The tracheae divide into smaller tubes called tracheoles which carry oxygen to the tissues of the insect body. The life cycle of Aedes mosquitoes consists of four stages egg larva pupa and adult with adults emerging anywhere from seven days to several weeks after egg hatching.

In anopheline larvae seta 1 may be palmate on some or all of these segments but this seta is never palmate in non-anophelines. Small openings called spiracles line both sides of the abdomen allowing the mosquitoes to draw in air. The mosquito larva has a well-developed head with mouth brushes used for feeding a large thorax with no legs and a segmented abdomen.
