Characters of the Anopheles and its Larva.
Anopheles are grey coloured gnats with often dappled wings and with palpi about the same length as the proboscis in both sexes.
Easy Characters :—
Proboscis al palpi look like a beak. Anopheles sticks out at right angles to any vertical surface to which it may be attachel.
Characters of the Larva :-
Larva swim parallel to the surface of the water, while Culex larva lang vertically downwards from the surface. Anopheles larvæ are found in green stagnant pools or at the green margins of swamps. Culex larvæ may be found anywhere in tubs, pools, &c.
Sucking of Blood :—
It is only the female Anopheles which bites a mammal, sucks the blood which it requires for the nutrition of its eggs.
