Post by: bio_man on Jan 1, 2022 These are called whirligig beetles. It is a type of water beetle. Here's some useful information on them: https://biology-forums.com/definitions/Whirligig_Beetle
The middle, and more especially the hind legs are adapted for swimming (natatory): they are greatly flattened and fringed with bristles that fold to aid swimming action. In contrast the front legs are long and adapted for grasping food or prey. In males the front tarsi (see image) have suckers, which are used to hold onto the slippery female during mating. The tarsus is also found in the image you provided.
