A study was carried out on aquatic insect, Dineutus sp, of Kangsabati River at two sites, Kangsabati Rail bridge region (site-A), Dherua Bridge Region (site-B) of district Paschim Medinipur, West Bengal. The sampling was done monthly from January,2024 to January 2025. Due to its inclination to gyrate or skate in schools supported by surface tension, the Gyrinidae family is known as the "Whirligig Beetles." Their antennae are small and stout, and their middle and hind legs have been reshaped to seem more like paddles than legs. Their eyes are split into two sections, the lowest of which is below the water's surface and the top of which is above it. The female copulates on the water's surface and lays her eggs on emergent vegetation stems a few centimetres below the water's surface. They are one of the most well-known water beetle groups, and when handled, they emit a pleasant odour. When we were studied in river Kangsabati, we were found this species. The aim of this paper is to give interesting fact of this insect species.
