Velvet ants are really pretty and, despite their ability to sting, are a favorite of many bug enthusiasts. But where are velvet ants found in the US? Let us check it out.
Have you ever heard of cow killer ants? Well, the name might sound highly intimidating, but these tiny insects are nowhere near capable of killing cows.
The cow killer ants are known as velvet ants and there are around 8,000 of these species worldwide.
In this article, we will share details that will help you know this insect better.
Are Velvet Ants Really Ants?
Velvet ants might look similar to big hairy ants, but these insects are a type of wasps.
If you look closely, you will notice that they have straight antennae, while the ants have elbowed-shaped antennae.
These wasps have a painful sting and are also commonly known as cow killers or cow killer ants.
Velvet ants have brightly-colored yellow and red bodies which are covered with dense hair.
They are considered solitary wasps and are often seen roaming around the yards during the months of July, August, and September.
Can They Fly?
The male adult velvet ants have two pairs of black and transparent wings. The female velvet ant, on the other hand, has no wings, and it certainly can’t fly.
Due to the absence of wings, the female look much similar to ants. The adults can be spotted flying around flowers in search of nectar.
Why Do They Mimic Ants?
Different organisms mimic each other as an adaptation to survive certain conditions and dangers. The female velvet ants mimic some activities of the ants to defend against potential predators.
One of the main reasons behind this is that the wingless females of this species can’t fly to safety when they are attacked, so they develop additional techniques to stay safe.
Moreover, ants are considered one of the hardest prey in the insect world. Their ability to lift heavy loads and fight in groups helps them repel many predators.
Therefore, mimicking an ant is certainly a smart idea on the part of the velvet ant.
Apart from mimicking ants, cow killers also show aposematic signals through their colors to warn predators that they are hard to eat.
These warning signals are seen all across the insect world, including in ladybugs and many species of butterflies
Where Are They Found?
The species of velvet ants are scattered across the world. The red velvet ant (Dasymutilla occidentalis) is a common one found all over the US.
You can see these wasps all throughout Missouri to Connecticut in North America.
In South America, you can spot velvet ant species from Texas to North Florida. They are also found in some regions of Australia and the UK.
What is Their Habitat Like?
Velvet ants usually do not build their own nests. They invade the nests of other insects, like ground-nesting bees, and lay their eggs near the existing larvae.
Once the eggs hatch, the velvet ant larvae kill and consume the larvae of the existing species that their parents had removed from the nest. In this way, these wasps are parasitoids.
Due to this tendency, the females are often seen near places where the hosts build their nests.
You can also spot them in sunny and dry areas where bees make their nests. Lawns, cemeteries, and non-shaded areas of forest are also ideal living spots for these wasps.
What Do They Eat?
Adult velvet ants mostly depend on nectar and water to fulfill their diets. This is not different from most other wasp species.
The velvet ant larvae, on the other hand, eat the host larvae and pupae to fulfill their nutritional requirements. Velvet ant larvae are parasitoids, a common characteristic in most wasps.
Are They Dangerous?
The male velvets ants can’t sting and will cause no harm to humans. However, the females are stinging insects that can deliver painful stings when they are threatened.
Their stingers are large, which these females also use as an ovipositor.
According to Schmidt’s sting pain index, the pain intensity of the bite is ranked 3 out of 4, where four is the highest and most painful.
But apart from the excruciating pain, the bites are rarely dangerous. In fact, the name cow killers is a bit of a stretch. Velvet ants are not capable of killing cows or even dogs or cats.
Frequently Asked Questions
Are velvet ants rare?
In the United States, you can find red velvet ants in Missouri, Connecticut, Texas, and Florida. They love to be around dry and warm areas like lawns and cemeteries.
There are many species of velvet ants scattered all over the world. You can find them in the UK and Australia as well.
Can velvet ants hurt you?
vMale velvets ants don’t sting or bite humans and are completely harmless. However, the females will deliver highly painful stings if they feel threatened.
Apart from the pain, it causes swelling, redness, and irritation in the wounded area. But thankfully, these bites are mostly not dangerous and won’t cause any serious trouble.
Can you touch a velvet ant?
You should not try to touch or hold velvet ants, especially the females. These insects are usually non-aggressive, but if they feel threatened, they will certainly sting you.
Their sting can inflict a great amount of pain. If you want to touch them, it is better to wear gloves so they can’t reach your skin and sting.
Can you keep velvet ants as pets?
You should not keep velvet ants as pets because the females will sting you and your family members.
Adding to that, these stings are highly painful and will cause severe redness, swelling, and irritation.
The males, on the other hand, are equipped with wings which means they will keep flying around your house like pests.

Wrap Up
Velvet ants are quite common in the US, but outside, they are only found in the US and Australia in limited spots.
They get their name due to their ant-like appearance and the thick coat of hair covering their brightly-colored bodies.
The males and the females have different features which they use to survive against predators. The female velvet ants are capable of delivering painful stings to humans and pests. Therefore you must never handle them recklessly.
The bites can cause other problems like irritation, redness, swelling, and more.

I seen this exact one crawling into my backyard my husband has it in a plastic bottle and took it too work. It is indeed a velvet ant. Scary. Now i have to keep an eye out on my daughter when she is playing outside.

I’ve heard stories of cows actually eating these (by accident) while grazing and were stung in the throat when being swallowed and did indeed die. Just a story-not much proof but something to consider.
Many years ago when I was 9 or 10 years old I saw one of these velvet ants for the first time. It was beautiful so I scooped it up in my hands to take home to show my mother. Before I made it home it stung me and I can say that it was the worst insect sting that I can remember, but I did not die. 🙂 I see them frequently and let them go on their way.
My father pointed one of these out to me when I was about 4 years old on a farm in Delaware. The thing that shocked me the most (and makes me avoid all wasps like the plague) was how it stings. He took a piece of styrofoam and agitated the thing until it reared it’s abdomen above its head and the styrofoam actually vibrated as it was attacked. He called it a cow killer too, but didn’t say it could kill them, it would most likely make them bolt once stung, like a snake could, and that stinger would get through their hide on their feet.
Dear shadowspawn,
Thank you so much for this anecdotal information. First hand observational information like this is so important to our website.
In south Georgia in the early ’60s, farmers used to tell me that this wasp got its name by getting into the cloven hoofs of cows and stinging them there. The cow would then run madly off and sometimes be injured or fall, breaking it’s leg. Thus the name, as the lame cow would then have to be put down.
This is just about the best and most plausible explanation of the common name Cowkiller we have ever heard.
This story is indeed about as close to fact as possible. The hoof is one of the few places where the cows couldn’t do a thing about the wasp, as it couldn’t be reached. This is a great site Bugman, I expect to learn quite a bit. South Florida certainly has its share of native and non-natives to keep us guessing, and your site is a tremendous tool for identifying these multi-legged/antennaed/eyed/winged/ etc etc little monsters! LOL Thanks!
I nearly picked one up the other day but my daugheter stopped me. We made a comic after finding the name “cow killer” on this site.
Thanks, BugMan.

We just linked back to your comic on a recent posting of a gorgeous Cow Killer.
These things are so hard to kill !!! You have to put complete pressure on them and still step on them and move your foot about 10 times before you can actually kill them !! I hate being mean and cruel, but I am one who cannot stand spiders, insects or anything of the nature! I have two sons, one who is 6 and another who is 2, and I am scared they may have an allergic reaction and I hate making them put shoes on when going outside to play, we have a small farm and it seems like we find these cow killers, especially around my flower beds around the front porch!
My first encounter of this colorful and beautiful insect was in Arkansas. I am not a cruel person either,but I did try to step on it. It did nothing. I tried to stomp on it and it was still very much alive. I finally had to get a large tool to kill it. I had no idea what it was. A local person told me about this cow killer and after I looked up the information about it I stay very clear of it and the male that flies.It indeed was extremely hard to kill. I truly hope I never experience it’s sting!
This appears to be either Dasymutilla cressonii or a close relative.
Thanks for all your Velvet Ant corrections.
If you are still interested in identification, I’d say it more closely resembles the female of Sphaeropthalma pensylvanica.
Thanks for the correction
The velvet ant is Dasymutilla aureola.
Thanks for the identification.
Hi, it looks like an velvet ant for me too because of the furry appearance. But later i’ve been told that this is probably an ant from the Echinopla genus, maybe a Echinopla Melanarctos.
In our defense, Ants and Wasps are more closely related than either Ants and Bees or Wasps and Bees. Thanks for writing back with an identification. Here is a link to AntWeb:
http://www.antweb.org/description.do?genus=echinopla&name=melanarctos&rank=species
P.S. The species name or second name in a binomial identification is not capitalized, so your ant is Echinopla melanarctos.
I messed around with what looked like and probably was a cow killer in south GA when I was about 12. I tried to kill it but couldn’t so I put a glass over it on the ground where I found it. It was very agitated from my messing with it and started to make a loud, for a bug, noise. I left and returned later that day to find some ants trying to get to the killer. It was still making that noise and it seamed as if the ants were responding the cow killers calls. Are ants attracted to cow killers distress calls?
We don’t know, but perhaps one of our readers will be able to provide some information.
Dude, I thought this was a velvet ant too because of it’s furry appearance and they are always seen scavenging alone.
Most likely the ants responded to the wasp’s distress call in hope of finding prey for their colony.
This is the first I’ve seen this site and I like it! I moved to Northern Florida last August from northwest Pennsylvania. I know all the bugs and animals and trees and flowers, etc. from that area. BUT, I have no idea of all that is here in Carrabelle, Florida, in the water or on land. It just so happens that one of my neighbors pointed out a cow killer to me 3 weeks ago. He said he hadn’t seen one in years but that I should stay away from them. He also said that they are almost impossible to kill.
I was just walking out in my back yard, with my little dog, when I came across one by my bird bath. Of course, I was freaked out and tried to kill it before it would hurt my dog. I could not kill it by stepping on it so I finally found a discarded oyster shell and cut the horrible creature in half. It still is living!!!! How can I get rid of it?!?!?!? I didn’t used to be a ninny up North but I am still trying to get used to the strange wildlife here. Don’t get me wrong …. I love my home and the people and the area, I just don’t want to get hurt. I am a 64 yr. old woman and loving to learn about new things.
We do not give extermination advice.
I’m northerner living in South Carolina and just came across one of these cow killer bugs while I was out searching the yard for a snake that had just bitten my dog. “Crazy Day” .Just would like to say that after reading your forum I’m feeling much better knowing more information about these insects. There seems to be so many different kinds of hazards living in the south. Thanks for the info
The sting is reported to be extremely painful, though standards of pain can be quite relative.
If you enjoy learning, please learn to not kill any bug due to fear or possible ignorance of its’ capabilities re harm to humans. I thank you, as do the crawly creatures.
Why would you kill an insect outdoors…or—in most cases— indoors, for that matter? Velvet ants won’t sting if they’re not being messed with. Instead of killing them out of some wrongheaded fear for your children’s safety, wouldn’t a better approach be to teach your children not to touch them but to appreciate them? They are a stunningly beautiful insect, and you should feel fortunate to see them…and teach your kids the same. Regardless, this site isn’t the proper forum to post about the difficulty of killing them.
Thanks for providing your comment. Though we try to educate the public to appreciate and respect the lower beasts, in many cases our efforts are futile.
Traumatomutilla sp.??

Thank you. That does look like a very good match.
I was told that if a cow were to lay down on the “cow killers”nest, or pile, that they would get stung so many times that it would die. Now I don’t know if these”cow killers”have nests, or if they live in colonies?
They are a solitary species. We believe that you have heard a greatly exaggerated account.
We saw one of these today at a state park in Delaware. It was quite fast and it we just observed it. We noticed it when it was about six inches away from my 76 year old mom’s foot. So glad she didn’t agitate it or get stung by it! It was an incredible looking insect. Thanks for helping me identify it on this site! Great info!
I just saw one of these today, in my front yard in Dover, Delaware. It was indeed beautiful. I wanted to capture it, to photograph it, never having seen anything like it before. I thought about picking it up, but it looked wasp-like, and such a brightly colored insect reminded me of poisonous frogs. Glad I chose to run for a glass jar to capture it, but sorry to say it disappeared before my return.
What a treat, just to see something so beautiful. Beauty is everywhere, isn’t it?
We are gladdened to hear of your enthusiasm.
Perhaps this story is unfit for your readers, but I thought you might enjoy it. One of my first jobs out of college was as a botanist in SE Oregon. The first day in the field my boss went with me to “show me the ropes”. This part of the state is very sparsely populated and we were in an area at least 50 miles from the nearest civilization. I was examining a rare plant when my boss suddenly let out a scream I can still hear, yanked down his pants and began leaping about in a most fantastic manner. Turns out a velvet ant had crawled up his pant leg and stung him on a very sensitive part of his anatomy (unfortunately, I actually observed the offending creature et al.) I had to drive him back to the office with the contents of our ice chest held firmly in his lap.
The funniest part was how from that point onward he avoided contact with me at all cost and I was free to do my job without any supervision.
As sting and bite stories go, that is right up there with Centipede in her Panties.
Thanks but im not in california im in kansas and ben seeing more of these latley
I can attest to the VERY painful sting, I stepped on the fuzzy kind, magnifica I guess? But I remember it made a strange sound too. I live in Texas and have seen them around Dallas/Fort Worth and Waco as well.
I found just such an antwasp yesterday (24-1-15), I discovered it as it was stinging my thigh. I can say that the sting was quite painful, a bit like the sting of a common wasp, and it leaves a small mark like a big mosquito bite. It still very vaguely hurts now, but nothing to get excited about. I released it as it caused me no harm.
The location was Kadesh Barnea.

We too have noticed a Cow Killer here in our backyard in Charlotte, NC. We have young Grandbabies and a small dog. All the information here on your site is great. I have to say that before I knew what this insect was I was able to have it climb onto a toy and I placed outside of our fence, it didn’t seem aggressive, but did move very fast She returned and graced us with her presence yet again today. I don’t want to kill her…I live all creatures but, also don’t want our Grandbabies, one of which is very highly allergic to bites, or our small dog stung. What can anyone suggest to keep them at bay? Very concerned! Thank you
We know of no methods that repel Cow Killers without harming them or other insects.
I came across this while trying to ID an image of the same insect, thought I’d share that I found a potential exact match: Mutilla quinquemaculata. Compare to the images here: http://www.biolib.cz/en/taxon/id281310/
Thanks so much for providing the link to the identification.
Yeah, it’s A velvet ant. I saw one today while hiking in the Indian canyons in Palm Springs. I took some pics and it’s a cool bug.
I haven’t seen any Cow Killers this year yet. It was late in July last year before they appeared and was wondering if later in the summer is when they are out? Thank you
We suspect they tend to appear when weather conditions are correct. According to BugGuide, Florida sightings have been reported from April to September. Other states data are listed as well. You did not provide a location.
I have lived in Florida for almost 50 years and have played with these ants (wasps) my entire life. They do give a distress “squeak” when held down with a twig and that is a good way to see their amazing stinger in action. I am an avid outdoorsman and have been stung or bitten by just about every bug in Florida over the years. As a teenager, I was stung several times by a very large cowkiller (we called them Devil Ants) when I put on a shoe I had left outdoors overnight. It was very similar to being stung by a honeybee or large hornet. The four sting sites became swollen and feverish over the next few days. It was painful for sure but nowhere near the sting of a bumblebee. I once took a shot from a bumblebee under my armpit while working and it left a hole in me that you could put your little finger in. The cowkiller was a piece of cake compared to that one. It is similar to a typical large wasp sting.
Just saw the same in Tombstone, AZ…but different from what I had seen before as a velvet ant
According to BugGuide, there are 480 species of Velvet Ants in North America. There is also much visual diversity among them.
Located this insect while hiking in Menifee Ca.
It hurts?
My husband and I just witnessed a cow killer carry off a beautiful garden orb spider that had created a web next to the back door. It was a sad sight to see. The spider was pretty big maybe the size of a half dollar but the cow killer was dragging it across our deck. This was a male because it had wings. We live in northeastern coastal NC. This summer is the first time I’ve seen these insects.
We suspect you saw a Spider Wasp in the family Pompilidae and not a male Cow Killer. Male wasps do not provision nests and according to BugGuide, the Cow Killer “Invades the nest of bumble bees, especially Bombus fraternus. Female finds a host nest, digs down and deposits one egg near brood chamber. Larva enters the host brood chamber, kills host larvae, feeds on them, then pupates in the brood chamber.”
I found one and got a few photos in my family’s village Near Nafpaktos on the Greek mainland.
Hes actually pretty funny!
got 1 caught in a cup right now, female i guess (no wings). thanks for helping to ID it.
My family and I just saw one in Menifee, CA.
I just had one of these ‘fine specimens’ join me to bed; Eastern/Tri-Cities Tennessee; what a sting that left!
We also have then here in New Mexico. I spotted one at Truth and Consequence at Elephant Butte.
I found one in Smithville Missouri
I had one outside my house today. In Grand Junction Colo. Its not here any more I thought it was a baby tarantula OMG.
I found one in Kingman AZ this evening also thought at first glance it was a tarantula, that thing is sure fast we have had a lot of heavy rains lately wonder if reason why
We know rain is a stimulant to both Tarantula and Trapdoor Spider activity since that is when males travel in search of a mate. We don’t know if rain stimulates Velvet Ants in a similar manner.
Had one here in Calimesa,CA. I have never seen one of these before.
Just got stung by one of these picking up my child’s diaper! I’ll say I’d rather stand in a red ant hill for a few seconds than be stung by that thing again..that hurt. -Texas
found another one in Menifee, Ca.
Walking our dog in a sunny morning cemetery I spied a pale green fuzzy ant (?) a little less than
5/8 of an inch long, trucking along quite purposefully on the asphalt…It looked like a tiny toy, but no visible legs or eyes…I’ve seen other large “velvet ants” that were red and black, but never this lovely soft green…Sorry to have missed a chance for a photo…Can’t seem to find anything like it
on any of the bug websites…
We saw one at horseshoe bend in page arizona a few days ago.
I have some in my yard in perris california zip code 92570
I enjoyed all the anecdotal info. I still don’t know very much about the cow killer especially where they create their nests. How large are the nests. I live in central Virginia and see them usually in late July anD August. They are fascinating insects and I have found that they make a noise almost like a scream and you will not likely squash one because they are incredibly tough. I know that most posters do not like to kill any of nature. I too like to observe nature and usually have no desire to kill. But if there is any danger to me or family on my property they will go to insect heaven.
Cow Killers do not build nests. According to Texas A&M Agrilife Extension: “Life Cycle: Females seek the immature stages of ground-nesting bees, digging to the nesting chambers and eating a hole through the cocoon. She deposits and egg on the host larva, which soon hatches into a white legless grub. The immature velvet-ant eats the host larva, developing through several larval stages before forming a pupa.” According to BugGuide: “Invades the nest of bumble bees, especially Bombus fraternus. Female finds a host nest, digs down and deposits one egg near brood chamber. Larva enters the host brood chamber, kills host larvae, feeds on them, then pupates in the brood chamber.”
We just saw a yellow velvet ant at Lyman Lake (northeast Arizona, Apache County).
Spotted another of the big fuzzy ants yesterday morning, same general
location, except it wasn’t a very pretty color, sort of faded, no-
color…Watched it awhile, to see if it had a mate or companion…
Fascinating little critter…
