Abedus is a genus of giant water bugs (family Belostomatidae) found in freshwater habitats in southern United States, Mexico and Central America.

[6] Members of this genus generally do not fly,[7] and at least some species, including A. herberti, have a greatly reduced flight apparatus and are completely flightless.

[8][9] Despite being essentially aquatic Abedus may travel some distance overland and have been known to abandon streams after heavy rainfalls, allowing them to avoid being swept along in flash floods.

[11] Because of the unusual breeding behavior, especially A. herberti is often displayed in zoos, sometimes together with the sunburst diving beetle.

The only prey they regularly catch alive (not just scavenge) in the largest category is nymphs of their own species.
