Culex and Anopheles are yellow-ish, but you can identify them by observing their resting position. Anopheles mosquitoes have a ~45 degree angle, while Culex stay parallel to the surface. Microscopically, look for antena morphology. To identify instars, just look at the size and the color of the larvae.
How do you identify an Anopheles larva?
In the larval stage, mosquitoes can be identified by: a well-sclerotized head that is clearly separated from the thorax; legless thoracic segments that are little differentiated from each other; and an abdomen made up of 10 segments, but with only nine apparent.
