Anopheles: Hatching of the Imago
The egg cells of the anopheles mosquito require blood to mature. Its proteins are used in synthesising the yolk material. Fertilisation occurs only just before the female mosquito lays its eggs on the water’s surface. The eggs are equipped with the flotation chambers and fringes that are typical for the genus Anopheles. Thus, they can drift on the surface and harden without sinking. The film sequence shows the laying process and the eggs floating on the water’s surface in macroscopic images. The hardening of the eggs is shown in time-lapse cinematographic techniques. Additionally, the particular characteristics of egg morphology are emphasised. From the film: Biology of the Mosquito.
