Red Velvet Ant

 The Ant That Isn't an Ant

I wish I could count how many times I've had run-ins with this little [insert expletive]. 

The first time I had ever seen one, it took me by surprise. I was actually lying on the couch, watching TV. 

Feeling something crawling on me, I naturally just reached over and rubbed it against my arm with my thumb.

Then, that slow motion "oh NO" moment of realization. The result of this lazy, unknowing reaction: a sharp, intense burning, almost as if a match were being held to my skin. A pain I can't recall ever feeling before or since. 

The worst thing? I didn't even slow it down. It just kept on going and I think I even made it mad. Of course I didn't let it get away—but it did take a small hammer to get it to stop moving.

It sounded like I smashed a piece of plastic too. I had no idea what this was or what it was made out of, but it was fast, armored, and in possession of a weapon that if scaled correctly, could easily wipe out a city.

If any of you have had a run in with this little gal, then you understand exactly what I just described. 

This ant, that's not really an ant, is a wingless female wasp in the family Mutillidae—specifically, Dasymutilla occidentalis—the species people call the “cow-killer” because of its notoriously painful sting. 

The down and dirty:

• Common names: Red velvet ant, Eastern velvet ant and Cow killer

• Parasitoid wasp, not a true ant. Females are wingless and roam the ground

• Females sting; males don’t. Males have wings and cannot sting

• Covered in dense, bright red-orange hair over a black body

• Females parasitize the larvae of ground‑nesting bees and wasps

• Known for a very tough exoskeleton, fast movement, and even stridulation (a squeaking warning sound)

• The sting is intensely painful but not actually dangerous to humans or livestock

As an interesting aside here, the venom this wasp injects is not toxic and does not actually cause any physical damage. It's binding to your nerve receptors in much the same way capsaicin (the heat in peppers) does. It's an interesting corollary showing the incredible redundancy, consistency, and efficiency of nature. 

These furry—almost cute and pet-able—little insects roam the ground looking for burrows made by bees and other wasps, in the hopes of laying an egg on their larvae. That egg, once hatched, releases the larva of another cow-killer that will consume the host larva and continue on with its life cycle. 

I have to say, nature is a beast. We as humans have tough lives, deal with a lot of things, but I'll take that over an insect's life any day.

You may be asking yourself why I'm making this post for a gardening blog. I mean after all, my encounter with this insect was indoors, not out in the garden. The thing is, I just never noticed them before. Not sure HOW I didn't notice them before, but I see them constantly now. Just about every time I'm out in the garden, they are there. Crawling around, vibrating their warnings, looking for holes to crawl into and while not aggressively coming after me, they are definitely in warning mode.

These days, knowing what I know, I just let them be. When I see them, I say hello little [expletive once more], take a step back and let them go about their business. 

I've been on the receiving end of that city‑destroying weapon they possess one too many times. They have earned the right, in my opinion, to have the right‑of‑way, I respectfully yield to them.

So, next time you are out and about, digging up weeds or planting new plants, remember, if you come across something that looks like a very large, but pretty and friendly red ant, you'll know to stand back and just admire it from afar.

I know I will…

Happy Gardening 🌱
