Abedus

Abedus is a genus of giant water bugs (family Belostomatidae) found in freshwater habitats in southern United States, Mexico and Central America. Sometimes called ferocious water bugs, these brown insects typically are between long, although A. immaculatus only is about , making it the smallest North American belostomatid and possibly worthy of separation in its own genus. Otherwise the different Abedus species are very similar and can often only be separated with a microscope. They will bite in self-defense, which is painful but not dangerous.

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