Abedus
ferocious water bugs
Abedus is a genus of giant water bugs in the family Belostomatidae, found in freshwater habitats of the southern United States, Mexico, and Central America. These brown insects are notable for their exclusive male parental care, where females glue eggs onto the male's back and males carry and tend them until hatching. Most species are flightless or have greatly reduced flight capabilities. They are sit-and-wait predators that capture prey with raptorial front legs and subdue it with a venomous proboscis.
