Water Bugs
These are all known as "true bugs", as opposed to beetles, flies, ants, etc. Both the larval and adult stages are aquatic, although only the adult stages are shown here. All may be found swimming or clinging to underwater plants and must surface to breathe. All are also strong fliers that are attracted to lights at night and have a painful and poisonous bite. Giant Water Bugs are known to feed on small fishes.
