In these insects, the volume of the film is small enough, and their respiration slow enough, that diffusion from the surrounding water is enough to replenish the oxygen in the pocket of air as fast as it is used. The large proportion of nitrogen in the air dissolves in water slowly and maintains the gas volume, supporting oxygen diffusion ...

Bugs of the genus Belostoma prefer lentic habitats with submerged or emergent vegetation and for overwintering the adults fly to ponds and slow-moving waters. During the springtime and the early summer they often fly to electric light-sources, thus they are also called "electric-light-bugs". [6] The life circle contains one generation a year.
