The lesser water boatman (Corixa punctata) is a water-dwelling insect of the order Hemiptera.
They normally grow to between 5 and 15 mm long, and are found in ponds, lakes and sometimes even swimming pools. The boatman feeds on algae and dead plant material. They have long hind legs which they use to swim on top of water. These powerful legs are covered in tiny hairs which helps them float on the surface of the water. The boatman's mating call, generated by rubbing the penis against the abdomen, is the loudest sound, relative to body size, in the animal kingdom.
They breathe oxygen by trapping air beneath their wing cases when they are on the surface as the oxygen is trapped by tiny hairs.
They are similar to Notonecta glauca, the water boatman or back swimmer by appearance, although these lesser waterboatman are herbivores and swim on their fronts. They are not related to Notonecta glauca, the water boatman or back swimmer.

“I think there’s never a man in Christendom
Can lesser hide his love or hate than he,
For by his face straight shall you know his heart.”
—William Shakespeare (1564–1616)
“We can never part with it; the mind loves its old home: as water to our thirst, so is the rock, the ground, to our eyes, and hands, and feet. It is firm water: it is cold flame: what health, what affinity!”
—Ralph Waldo Emerson (1803–1882)
“The utmost familiarity with dead streams, or with the ocean, would not prepare a man for this peculiar navigation; and the most skillful boatman anywhere else would here be obliged to take out his boat and carry round a hundred times, still with great risk, as well as delay, where the practiced batteau-man poles up with comparative ease and safety.”
—Henry David Thoreau (1817–1862)
