Seemingly awkward when swimming, it rarely leaves the water, doing so only when forced to fly to another pond to find more resources.

Its effective camouflage keeps it hidden from its most common predators and also from its own prey.

Insects capable of rapid growth and expansion can damage both environments and health,
and water scorpions play an important role in regulating insect populations.
As part of this process, huge numbers of mosquito larvae and pupae are eaten by several species of aquatic insects, before they even reach the surface.

Through the tube at the end of its abdomen, the Nepa draws air from above the surface while it remains below, lying in wait for its prey. Its prehensile forelegs trap anything within reach.
Its victim firmly clasped, it sucks out their insides through a tubular mouthpiece until its meal is completely empty.
