The Family Glossinidae is also commonly referred to as the Tsetse fly family. These bloodsucking insects are known transmitting diseases such as African sleeping sickness. Other synonyms for the term Family Glossinidae include Glossina, tsetse, and tse-tse. These names refer to the distinctive buzzing sound the flies make, which sounds similar to the 'tse-tse' we hear when someone whistles to get our attention. While these flies can be a nuisance and pose a serious health risk to both humans and livestock, they are an important part of the ecosystem, providing a source of food for predators such as birds and reptiles.
