WAquarius is a genus of water striders found predominantly in the northern hemisphere. Formerly a subgenus, Aquarius was elevated to generic rank in 1990 on the basis of phylogenetic analysis. These are among the world's largest water striders, with females averaging 12–17 mm (0.47–0.67 in) long and males roughly 10–30% smaller, depending on the exact species. An outlier is A. elongatus where both sexes typically are about 24 mm (0.94 in), roughly the same as certain Cylindrostethus, and second only to Gigantometra gigas.

WThe Gerromorpha comprise an infraorder of insects in the "true bug" order Hemiptera. These "typical" bugs are commonly called semiaquatic bugs or shore-inhabiting bugs. The Ochteroidea are also found in shore habitat, while the Gerromorpha are actually most often encountered running around on the water surface, being kept from sinking by surface tension and their water-repellent legs. Well-known members of the Gerromorpha are the namesake Gerridae.
WHalobates micans is a species of water strider in the family Gerridae. It is one of five Halobates species that live on the surface of the open ocean, only occurring near the coast when storms blow them ashore. Unlike the others that are restricted to the in the Indian and/or Pacific Oceans, H. micans is circumglobal, occurring offshore in warmer seas around the world. It is the only Halobates species found in the Atlantic Ocean where it ranges from about 40° north to 40° south.
