How To Identify Waterbugs

  • Giant water bugs (Belostomatidae)

Cockroaches

  • German cockroach
  • American cockroach
  • Oriental cockroach

For the purpose of this article, we will focus on the true water bug that resides in or around water.

Lethocerus Americanus
Binomial Name

Lethocerus americanus

Water bugs or Giant Water Bugs go by the scientific name Lethocerus americanus. They belong to the family Belostomatidae and are freshwater hemipteran insects. Toe-biters, Indian toe-biters, alligator ticks, or fleas are some of the most common colloquially used names.

Body Size

Water bugs are approximately 1.5 to 2 inches long

Body Shape

The body of a water bug consists of three parts: head, thorax, and abdomen. Their body is flat and oval-shaped and has a boat-like appearance.

Adult water bugs cannot breathe underwater, so a short breathing tube can be seen retracted into the abdomen. The tube functions are similar to a snorkel.

Overall, their body shape is well-suited for hunting, as the forelegs are modified into hook-shaped appendages to grasp and hold prey. The flattened hind legs resemble oars and are used to swim in the water.

Number of Legs

A giant water bug has six legs. The two frontal legs are hook-shaped appendages used to grasp and hold on to the prey. When the water bugs get hold of the prey, they inject a powerful poison that paralyzes the prey and liquefies its body.

The two hind legs are fringed and act as paddles or oars to keep the bug afloat.

Eyes

Most water bugs have 2 eyes. You can often see short antennae tucked behind the eyes of water bugs.

Color

Water bugs have a large body, typically brown or grayish in color.

Behavior

Giant water bugs are aggressive predators, and their menu is pretty long. They mostly feed on aquatic insects, fish, and amphibians. Even though water bugs are often much smaller than their prey.

Whilst waiting for their prey to come closer, water bugs often lie motionless, holding onto plants in a freshwater pond or stream. When the prey passes by, Belostomatidae strikes it using the forelegs and injects a powerful toxin.

Unlike most species, the male water bug plays a role in caring for the eggs and carries them until they hatch, whereas the females spend considerable time seeking out males to mate with.

Habitat

Water bugs, like their name suggests, spend most of their time in the water. They prefer warm and humid climates and are attracted to damp and moist areas with freshwater ponds, streams, marshes being home to most species.

Giant water bugs are common in parts of Asia as well as other tropical and temperate regions of the world.

Water Bug Vs Cockroach

Water bugs and cockroaches are often mistaken for one another, but there are a few noticeable differences between them:

Size

Water bugs are typically larger than cockroaches. Adult water bugs are about 2 inches long, whereas cockroaches are between 1 to 1.5 inches long.

Habitat

Both water bugs and cockroaches can survive in water, but cockroaches prefer dry land. Water bugs prefer warm and humid climates and spend most of their time in the water.

Food and feeding

Cockroaches are omnivorous scavengers and are not picky when it comes to eating. They consume any leftovers available to them. Conversely, water bugs hunt and paralyze their prey by injecting a toxin.

Behavior

Water bugs will bite you if it feels threatened. But cockroaches are mostly withdrawn, scurry away from bright lights and other species, and do not bite.

Pest Determination

True water bugs are not considered pests, as they don’t make life particularly difficult for humans. Whereas cockroaches are true pests and should be removed from domestic premises due to various health risks.
