There is an insect that swims near the surface of water with its upside down! It is called Backswimmer (Notonecta glauca). Though this aquatic insect resembles Water boatman, it is different: unlike water boatman it is a predator of tadpoles and small fish – a non-vegetarian. And it has specially adapted fringed hind legs for swimming. It can also fly. And it may bite us and give pain, if disturbed.
It is a wonder insect to watch in its action – back swimming!
