In turn, the mandibles of corixid bugs shared a common pattern with other water bugs , but Brozek  pointed out similarities in the mandibles of the corixids only with respect to the mandibles of the Gelastocoridae.
Those that remain submerged include fast swimmers inhabiting the open water, including the corixids and notonectids [38, 43-45] and slow-moving benthic species that breathe through long respiratory siphons, such as many nepids and belostomatids .
Some of the Nepomorpha species are mostly predators whereas most corixids are plant feeding; however, there are several species which prefer feeding on animals or a mixed type of nutrition [43-45, 49-51].
Several other invertebrate taxa (corixid
and gerrid hemipterans, dytiscid beetles) immigrate to the artificial ponds each spring, complete one or several generations, and then return to the natural basins to overwinter (Wissinger 1997).
