A backswimmer is any of a group of various aquatic insects of the family Notonectidae, which swim on their backs.
air bubbles
The backswimmer insect is named so because it swims backwards, unlike most other insects.

Notonecta backswommer What is "their" referring to?
Backswimmers are carnivorous, eating other insects, tadpoles, small fish and crustaceans. Researchers believe that backswimmers detect their prey by feeling vibrations made in the water by the other creature. Once the prey has been caught by the front legs of the backswimmer, it inserts its beak-like mouth and pumps digestive juices into its victim, dissolving the insides. The backswimmer then sucks out the digested innards.
no the reason is because back swimmers do not lay eggs. back swimmers only have live born. they are easy to catch tho. have fun if you try catching them when you are in the pool they tend to bite when they feel threatened.
all i know is the hectors dolphin which is an endangered species.Hectors dolphin Cephalorhynchus hectoriBlue Whale Baleonoptera musculusClown Fish Ocellaris opercula
Backswimmers move by rowing their long hind legs through the water in a sculling motion, using them as paddles to push themselves forward or backward. They can also glide through the water using their streamlined body shape to minimize water resistance. Additionally, they can adjust their posture to control their buoyancy and depth in the water.
Backswimmers have flattened bodies and long hind legs that are specialized for swimming. They also have piercing mouthparts adapted for predation, as they feed on small aquatic organisms like mosquito larvae. Their ability to breathe underwater using a plastron, an air bubble held under their wings, is another important adaptation.
I live in North Central Florida. The most common pest in my pool is the predacious diving beetle. These little bast- ... buggers will actively chase you down and take a bite. It hurts but I don't think they're venomous. I read they can get up to an inch long but I've never seen one longer than a 1/4 inch. I spend the first 5 or 10 minutes in the pool searching for these beetles then scooping them up in the net and crushing them on the side of the pool. I also frequently have backswimmer beetles in the pool as well but these generaly leave me alone unless I try to catch them. I caught one by hand once and he bit me hard. They have a long tube of a mouth they use to suck blood from their prey and he pierced my finger. I don't catch them by hand anymore. I just scoop them out with the net and send them on their way. It is rare but not unheard of to find an alligator in your pool so always give a quick check before jumping in.
