Aquarius najas, also known as the river skater, is a species of aquatic bug. It was formerly known as Gerris najas, but the subgenus Aquarius was elevated to generic rank in 1990 on the basis of phylogenetic analysis.
This species usually lives in the stony margins of rivers.
Aquarius najas spends the winter as adults. In the spring, they form pairs, and before mating, row about together on the surface during the daytime. At night, they separate, and the females lay their eggs beneath the water in closely packed patches. Normally the eggs are laid on the surface of flat stones.
