The Giant Water Bug

Arthropod Facts, Daily Critter Facts, Insect Facts

The giant water bug, aka Indian toe-biters, toe-biters, electric-light bugs, alligator fleas, or alligator ticks, are the largest insect in the order Hemiptera. They prefer to dwell in marshes, bogs, freshwater ponds, and slow-flowing streams. Giant water bugs are found in North America, Central America, South America, Europe, Africa and Asia. These aquatic insects are not currently evaluated by the IUCN.

First the Stats…

Scientific name: Belostomatidae
Length: Up to 4.5 inches
Lifespan: Up to 1 year

Now on to the Facts!

1.) There are approximately 170 known species of these insects.

2.) While nymphs can respirate (breathe) underwater, adults have to breath oxygen via a retractable tube.

3.) Most species of these insects possess front legs that have evolved into modified raptorial appendages that they use to grab onto their prey.

4.) An African species (Limnogeton) has normal forelimbs and is a specialized snail eater.

5.) Once a prey item (or a nearby toe or finger) is grabbed they are stabbed with a proboscis and a potent proteolytic saliva is injected, allowing the water bug to suck out the liquefied remains.

But wait, there’s more on the giant water bug!

6.) Some water bugs can fly, while others have underdeveloped wings and are thus incapable of flight.

7.) Fish, amphibians, snails, and crustaceans, baby turtles, and water snakes are all on the menu.

Did you know…?
In parts of Asia, giant water bugs are a popular food item. They are often fried in oil and sold at marketplaces.

8.) Even though their bite is horribly painful, their bite poses no medical significance to humans or large mammals.

9.) In an exhibition of parental care, females lay their eggs on the wings of the male, where they’ll stay until they hatch.

10.) It is the females who seek out males with which to mate. This role reversal is characteristic of R. L. Trivers’ parental investment theory.

11.) Giant water bugs are preyed on by birds, fish, and larger aquatic predators.

With over 50 years of critter experience to my credit and hundreds of zoology teaching hours to people around the world, I have amassed not only a continuing thirst for critter knowledge but a desire to teach others all I can about the majesty and wonder of our natural world. Critter Science is a culmination of such knowledge. I have hands on as well as book acquired intel on all kinds of critters. Whether they're on land, sea, or in the air. I will never say that I know everything about all animals. That's impossible, even for a savant. But, that being said, ask me any animal question and I'll answer it. If I don't know the answer, I'll get an answer for you!
