Unlike water boatmen, backswimmers do not have narrow, dark parallel line patterning on their backside; this is one way to tell the species apart. You can also distinguish them by watching their swimming style. Water boatmen swim right side up, while backswimmers swim upside down.
What is the difference between a backswimmer and a boatman?
The often red-eyed Water boatmen (family Corixidae) are a bit smaller than backswimmers. Collector-gatherers, they swim head down along the bottom in search of food.
What is a water boatman?
Water boatmen come in two forms- there are lesser boatmen and greater boatmen. Lesser boatmen are the bugs that swim on their front limbs, and greater boatmen swim on their rear limbs. Greater boatmen are called backswimmers because of this habit.
What is the difference between Lesser and greater boatmen?
Lesser boatmen are the bugs that swim on their front limbs, and greater boatmen swim on their rear limbs. Greater boatmen are called backswimmers because of this habit. They use their hind legs to swim across the water.
Are boatmen bugs the same as water cockroaches?
They’re almost similar to a water cockroach because their shape is so similar. Boatmen bugs are also known as Corixidae, lesser water boatmen, Arcotocorisa arguta, Corixa punctata, pool water bug, and also often confused with backswimmers. Water boatmen and backswimmers are not the same bugs.
What is the difference between water boatmen and backswimmers?
The backswimmer stores air in two hair-covered troughs on the ventral side of its abdomen (it can stay underwater for as long as six hours), and the water boatman wraps a bubble of air under its wings and around its abdomen and also picks up dissolved oxygen from the water (it is so buoyant that it must grab vegetation ...
What does a backswimmer look like?

What are these swimming bugs in my pool?
There are two main types of Waterbugs that you can get in your pool: Water Boatman and Backswimmers. They look a lot alike because they are both from the Hemiptera classification of insects. Water Boatman are oval-shaped bugs that are half of an inch long and are usually brown or brownish with a tinge of green.
What are the tiny things swimming in my pool?

How do backswimmers get in your pool?
Water boatmen and backswimmers are different. They are attracted to the pool as a habitat and want to be in the water. How do they get in? Typically, one of two ways: either they fly in, or they are born there.
Are backswimmers aggressive?
While backswimmers are aggressive predators, no doubt, they are by no means at the top of the food chain! Many species of fish, insects, and amphibians see these insects as a great meal.
How to tell if you have a backswimmer?
Here’s another way to tell the difference between these two aquatic bugs: if the insect in question bites you and it feels like a bee sting, you know that you have a backswimmer on your hands. Water boatmen are harmless to humans, and do not bite or sting. Backswimmers, however, are a different story.
What is a backswimmer?
Backswimmers are a family of aquatic insects that swim upside down , just as their name suggests! They are from the insect family Notonectidae, which is nested within the order Hemiptera. The name “Notonectidae” comes from the two Greek words “notots” (meaning “back”) and “nektos,” (meaning “swimming”).
How do backswimmers catch food?
In order to catch a meal, the backswimmer will dive down beneath the water’s surface to catch submerged prey. If the backswimmer is hanging out in the bottom vegetation, it can release its grasp and float upwards to catch prey that is higher up in the water column.
How long does it take for a backswimmer to produce?
Backswimmers complete their life cycle in approximately 6 months, so they tend to produce two generations per year. If the male is lucky in attracting a mate, the pair will undergo a mating ritual.
How long can a backswimmer stay underwater?
Backswimmers have a very unique and interesting adaptation that allows them to remain underwater for up to hours at a time. On the underside of a backswimmer, there are two thin channels; these channels are covered in very fine, inward-facing hairs. The backswimmer can use this area on its body to trap air bubbles!
What happens when a backswimmer pierces its victim?
Once the backswimmer pierces its victim, it injects digestive enzymes into the prey’s body cavity. These enzymes and chemicals cause paralyzation of the prey, and begin to dissolve its innards! The backswimmer will then suck the bodily fluids out from the body cavity.
What is the life cycle of a backswimmer?
The Life Cycle of Backswimmers. Juvenile backswimmers are typically white with red eyes. Photo by gailhampshire / CC BY-SA 2.0. Like all other “true bugs,” backswimmers experience incomplete metamorphosis – this means that they experience gradual developmental changes from egg to adult form.
What is the difference between a backswimmer and a water boatman?
Backswimmers are a lot bigger and bulkier. They also swim with their hind limbs. Water boatmen come in two forms- there are lesser boatmen and greater boatmen. Lesser boatmen are the bugs that swim on their front limbs, and greater boatmen swim on their rear limbs.
Why are boatmen called backswimmers?
Greater boatmen are called backswimmers because of this habit. They use their hind legs to swim across the water. To add to the confusion, there is also lesser backswimmer, which is smaller than regular lesser boatmen. Backswimmers are in a different family called Pleidae, while boatmen are in the Corixidae family.
What are boatmen bugs?
Boatmen bugs are also known as Corixidae, lesser water boatmen, Arcotocorisa arguta, Corixa punctata, pool water bug, and also often confused with backswimmers. Water boatmen and backswimmers are not the same bugs. They have differences between their habits, appearance, environment, characteristics, and morphology.
Why do you need a cover for a pool?
This will keep water boatmen out and keep your pool safe from sunlight, which will only make algae grow faster. A pool cover is a necessary purchase for any pool.
How do water boatmen get into a pool?
Water boatmen get into your pool simply by flying. They have wings for flight and are capable of swimming and diving underwater by grasping an air bubble. So they could be looking for food to eat or possibly scouting out an area to hatch water boatmen nymphs.
What is a water boatman?
Water boatmen have a distinct, elongated shape that resembles a cockroach. They’re about ½” in length at full maturity with short front legs. They have a shovel on their front legs that they use to scoop up food. The hind legs are miniature “oars” that they use to swim, similar to paddles used for boats.
Why do nymphs dart to the water?
Nymphs dart to the water surface more often compared to adults because they can’t hold their breath. Over time, boatmen will mature and swim fewer times to retrieve oxygen. Adults are identical to nymphs other than size and a developed wingspan. Nymphs will molt 3 times and grow wings as they mature.
