Anopheles mosquito. Coloured scanning electron micrograph (SEM) of a female Anopheles gambia mosquito. The SEM shows the mosquito's head (centre), part of its body (lower right), its legs (bottom), and its wings (centre left and centre right). Structures on its head include its large compound eyes, two antennae (upper left), and a long proboscis (centre right). This proboscis is used to feed on blood, such as that of humans. A. gambia is found in Africa, where it is a vector for the Plasmodium protozoa that causes malaria. Magnification: x52 when printed 10cm wide.
