Abstract
Tsetse flies successfully exploit seemingly precarious habitats in Africa at extremely low population densities. They possess no sex pheromones (Dean, et al, 1969; and there may be less than 20 males per square kilometer (Glasgow, 1963: 192), yet all post teneral females are found to be fertilized (Vanderplank, 1947). One means by which several species ensure sexual encounters under these circumstances involves a unique behavioural system known to field entomologists as the "following swarm".
