False colour SEM of the head of a tsetse fly
False-colour scanning electron micrograph (SEM) of the head of a tsetse fly Glossina morsitans, a large bloodsucking fly of tropical Africa. The tsetse fly transmits a parasitic protozoan called Trypanosoma, of which T. gambiense & T. rhodesiense are the agents of sleeping sickness in humans. Both male & female are bloodsuckers. Their habitat is varied, ranging from forest to river bank to savanah. Unlike most flies the tsetse gives birth to fully developed larvae, which immediately pupate. The female nurtures one larva at a time, with a total of 8-10 per lifetime. The short antennae are adorned with bristles called aristae. Magnification: x14 at 6x4.5cm size

EDITORS COMMENTS
This print showcases the intricate details of a tsetse fly's head, captured through false-colour scanning electron microscopy. Glossina morsitans, as this large bloodsucking fly is scientifically known, resides in the tropical regions of Africa and plays a significant role in transmitting Trypanosoma, a parasitic protozoan responsible for causing sleeping sickness in humans. Both male and female tsetse flies survive by feeding on blood. Their adaptable habitat ranges from lush forests to river banks and vast savannahs. Unlike most flies, the tsetse possesses an extraordinary reproductive process; it gives birth to fully developed larvae that promptly undergo pupation. The female diligently nurtures one larva at a time throughout her lifespan, which typically amounts to 8-10 offspring. Noteworthy features of this remarkable insect include its short antennae adorned with bristles called aristae. This image provides us with an up-close look at these fascinating characteristics while magnifying them fourteen times their actual size. Through this stunning photograph from Science Photo Library, we gain insight into the world of nature's tiny wonders and appreciate the complexity of our ecosystem. It serves as a reminder that even seemingly insignificant creatures like the tsetse fly play crucial roles within our environment—roles that can have profound effects on human health and well-being if left unexamined or misunderstood.
