Water treader

1 or 2, see text Water treaders, the superfamily Mesovelioidea, are insects in the order Hemiptera, the true bugs.

Females are larger than the males of their species and have well-developed ovipositors.

[1] The type genus, Mesovelia, contains about 27 species, many of which are common and widespread.

It is a legitimate binomial name following the International Code of Zoological Nomenclature, featuring aaa, the Hawaiian word for "lava tube".

[4] The family Madeoveliidae is often treated as a subfamily of the Mesoveliidae, but molecular studies suggest it is phylogenetically inconsistent, and thus suggest to abandon dividing the two.
