The most distinct feature of the wheel bug is also what gives the bug it’s name: the "cogwheel" on its back.

Learn More About Wheel Bugs

The wheel bug looks like something out of a sci fi horror movie and homeowners often wonder what they're seeing is real. Arilus cristatatus, more popularly known as the Wheel Bug is a fierce garden predator and is--oddly enough when it comes to how it looks--regarded as a beneficial insect.  The wheel bug earned its name from the frightening looking wheel-shaped armor found on its back. This makes the wheel bug particularly stand out because there is no other insect native to North America that has this type of body feature.

What's the wheel there for? That's not exactly known but entomologist guess that it may be used as a signal to other insects to stay away or it may be an instrument used to attract a mate, either way it gives humans the impression that it spells trouble if they are found on the property. Aside from this, the wheel bug also emits a weird aroma that comes from scent glands on its abdomen that is believed to be used to warn potential predators that they won't like its taste.

Wheel Bug Appearance and Behavior

With bodies reaching as long as 1 and a half inches long, the wheel bug is one of the largest true bugs in North America. It also comes from the Reduviidae family, which makes it a variation of the assassin bugs and kissing bugs. Assassin bugs are known for their predatory habits, stalking their prey closely and waiting for the right opportunity to pounce and devour the unsuspecting victim. Wheel bugs inject a powerful poison from their ‘fang' called a rostrum which turns the internal organs of the unfortunate victim into liquid. Once reduced to a drink, the wheel bug eagerly sips their dinner from the shell of its prey.

Wheel bugs are found all across the United States. The North American wheel bug does not like to be seen and is such a great hider that many people have never seen one. They do not like to multiply in large numbers so chances are you'll never see more than one or two in a season and don't have to worry about some alarmingly huge infestation (thank goodness).

Thankfully, wheel bugs are not aggressive toward humans and move slowly, almost robotically. They only bite in self-defense when they feel threatened so as long as you let them do their thing and don't bother them, they'll leave you alone.

Wheel bugs have the ability to fly but are a bit clumsy in execution so they prefer to walk and will even climb trees to search for prey. Its grayish-brown body blends well with tree bark and leaf litter, so you may touch one without realizing it. Creepy, right?


In gardens, they are known to eat bugs which like to damage plants, which is why they are seen as a beneficial insect. Some of their favorite foods are Japanese beetles, aphids and tent caterpillars. If you can overlook its frightening appearance and don't try to handle it due to its painful bite, consider the wheel bug a free, all-natural pesticide. 


Wheel Bug Life Cycle

Wheel bugs have only one generation a year and wheel bugs nymphs hatch out each spring from eggs that have overwintered. The female deposits the small, barrel-shaped eggs to twigs and branches in autumn where they spend the entirety of winter. 

After about 100 days, the nymphs transition from hatchlings to adults, which means they are mostly spotted in late summer. Nymphs go through about 5 different instars (or stages) and do not get their 'wheel' until they are fully grown. The small nymphs are also highly predatory and feed on aphids and small caterpillars.

While not necessarily nocturnal, you may notice them at night because some of their favorite prey are attracted to the lights over your garage or front porch.


Wheel Bugs Bite And It Hurts!

Gardeners are warned not to handle or disturb this insect, as its bite is painful and often described as worse than a bee sting, sometimes resulting in a scar. Some pest control experts who have experienced a bite have gone so far as to compare it to being shot by a bullet, although the pain didn't last as long. It is safe to assume that they wouldn't make the best pets. Its range is widespread and reports from all across the US and Mexico let us know that it can survive in a wide range of environments.
