Mosquito. Coloured Scanning Electron Micrograph (SEM) of the head of a mosquito, Anopheles sp. , which spreads malaria. The insect has compound eyes (blue). Emerging from the head is a characteristic three-pronged fork (at centre) which consists of two mandibular palps and the piercing proboscis. The proboscis is used by the females of the species to draw blood. There are several Anopheles species which transmit malaria. The parasite that causes the disease is present in the saliva of female mosquitoes. Malaria is a major health problem in many countries, causing a potentially fatal fever.
