Eggs and a newly hatched larva of the mosquito Anopheles stephansi on the surface of a pond. The eggs are delicate and spindle-shaped and are kept afloat by a girdle containing air chambers. They can be seen floating singly,often close together in large numbers. The larvae hatch and float horizontally just below the surface of the water. Their mouthparts bear combs of hairs which beat through the water filtering out algal spores,scattered pollen,bacteria and other micro- organisms. They moult several times before pupating | |
