Larva

Consists of head (caput) , thorax, and abdomen

The head is quadrato-ovoidal in shape, and issomewhat dorso-ventrally flattened, it has a pair ofshort, shaft-like antennae

The thorax is quadrate, compressed dorso-ventral,and broader than long

The abdomen is more or less cylindrical but tapersomewhat caudally. The last 2 segment are bent

ventrally and bear 4 anal (or tracheal) gills. In theculicine mosquitoes there is a siphon tube arisingfrom the eight segment. In anopheline however thissiphon is not present.

No siphon, spiracles almost flush with surface of eightsegment

No comb

has palmate hair tufts on the dorsum of abdominal

segment

The resting anopheline larvae are suspended horizontally
