Tsetse can be distinguished from other large flies by two easily-observed features: primarily, tsetse fold their wings over their abdomens completely when they are resting (so that one wing rests directly on top of the other); Secondly, tsetse also have a long proboscis, extending directly forward, which is attached by a distinct bulb to the bottom of their heads.
