The tsetse fly is a large, blood-sucking insect found primarily in sub-Saharan Africa. It belongs to the genus Glossina and is known for its role as a vector for diseases such as sleeping sickness in humans and Nagana in livestock. Tsetse flies are typically found in wooded and savanna areas, where they thrive in warm climates. Tsetse flies are characterized by their distinctive appearance, with a long, slender body and a unique wing structure that folds over their backs. They are attracted to movement and dark colors, making them more likely to bite humans and animals. Control measures include traps, insecticides, and the use of protective clothing.
