Streamlined, oval aquatic beetles with a smooth but often keeled back. The back is keeled like the bottom of a boat and lacks narrow parallel lines. Beetles are found on land and in fresh water and can adapt to almost any environment. Scarabs, stags, and bess beetles are a cosmopolitan group of beetles that are characterized by an antennal club that is lamellate, a thorax that is modified for burrowing, and by the C-shaped, cream-colored immature stage (often referred to as larvae or white grubs). Stonefly nymphs develop slowly, taking 1 to 3 years to molt repeatedly before emerging as adults. These beetles are found swimming in marshy freshwater ponds throughout the world, especially in warm regions. Water scavenger beetles hang out along pond and lake edges. Silphids, which dig under small dead animals so that they settle into the ground, lay their eggs on the carrion, on which the larvae feed.

Water scavenger beetle, any of the approximately 3,200 species of the predominately aquatic insect superfamily Hydrophiloidea (order Coleoptera). They range in length from several to about 4 cm (up to 1.6 inches). Backswimmers rest at the water surface tilted head-downward, with the abdomen tip protruding from the water. But now, R. attenuata is giving this beetle clan a new claim to fame – thanks to the ability to quickly wiggle its way out of a frog butt after being eaten. These characteristics lead to several interesting facts about Hercules beetles. Water bugs are usually about two inches long. Even though they were very closely related, they didn't look anything alike. Many larvae must come to the water surface for air, although a few (e.g., Berosus) breathe through the body wall and abdominal filaments. If a predator such as a bird approaches from above, the beetle dives below the water. The number of species in the Tenebrionidae is estimated at more than 20,000 and the family is cosmopolitan in distribution. Though tiger beetles are closely related to ground beetle, both the groups differ in the shape of their body. As with other aquatic insects, these beetles are a healthy component of ecosystems that produce fish, waterfowl, and many other animals we enjoy. Moreover, they create their own vibrations and process the returning echoes to detect prey or find mates. The water scavenger beetle swims by moving the middle and the hind legs on each side together. Fjords influenced by relatively warm Atlantic waters, both in Norway and Svalbard, had high scavenger richness.

Notes - Water scavenger beetle larvae can often be difficult to identify below the Family level. Corrections? The insect can store a supply of air within its silvery belly, much like a deep-sea diver stores air in a tank. Even when shrimps were captured, their shells could not be destroyed in the closed state; when one mandible was inserted between the shells these could be destroyed and the contents digested.
