Way of life
They are good fliers and so colonize newly furnished garden ponds, they also fall every now and then by mistake on glass surfaces of greenhouses. Wassertreter breathe atmospheric oxygen, they renew the abdomen end at the water surface and store under the elytra and the powerful disc-shaped rear hips.
They are found in slow-flowing or stagnant waters, where they feed as herbivores more crawling than swimming underwater vegetation graze ( algae), or small crustaceans, worms and mosquito eggs. Eggs are laid on water plants.
Their larvae suck with highly specialized mandibles ( Saugmandibeln ) on algae and remove the dissolved oxygen in the water through the body surface.
Pre- grown they pupate in a burrow on land.
