Aquarius (bug)
Aquarius 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 long and males roughly 10–30% smaller, depending on the exact species. An outlier is A. elongatus where both sexes typically are about, roughly the same as certain Cylindrostethus, and second only to Gigantometra gigas.
