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.
