Swarms - they don't swarm in the traditional sense of many flies attacking the same person, but they do form "following swarms" that can track a host.





Eggs - tsetse flies do NOT lay eggs in human skin. The eggs partially develop in the mother's uterus, and then are laid into the soil where they continue to mature.





Death - tsetse flies do NOT die under human skin. They can bite humans and infect them with various infectious diseases (especially trypanosomiasis), but they never actually enter the human host.
