It is found throughout Western Europe, up to Asia, in any kind of reservoirs with stagnant water or a weak current, where there are many small aquatic insects , small fish and frogs . Like all species living in the water, their body has an elongated shape, allowing you to easily move in the water. Coloring - from dark brown to black, legs - yellow with a wide orange-yellow edging all over the body and head. Males are smaller than females, and they can be distinguished by smooth elytra, called eliters. Both male and female have large, wide, flat heads, strong forelegs and sharp powerful mandibles for cutting prey. Also, swimmers can fly well, but rarely do this, mostly when their living conditions in the former reservoir become unfavorable and there is a need to move to another reservoir.
Size: 27–35 mm. [2]
There is a larger subspecies (31-37 mm), found in the Far East . [2]
