Today, we’re diving into the fascinating world of bullet ants. These remarkable creatures are known for their incredibly painful sting, which is said to feel like being shot by a bullet. This intense pain is why they are aptly named “bullet ants.”
Bullet ants are among the largest ants in the world, although there is another genus called Dinoponera that can be even larger. However, Dinoponera’s sting is not as painful as that of the bullet ant. The scientific name for bullet ants is Paraponera clavata, and they are a subject of interest not only for their size but also for their venom and gut bacteria.
In our research, we aim to study the venom of these ants. Initially, we attempted to extract the venom by bringing the ants back alive. The process involves encouraging the ants to sting through a tube covered with parafilm, a waxy material. The idea is for the ants to deposit their venom on the side of the tube, similar to how venom is extracted from spiders.
Interestingly, bullet ants are highly aggressive in the wild, immediately going into attack mode when disturbed. However, after spending some time in the lab, they become almost docile, making the venom extraction process more challenging.
During the extraction process, we observed the ants stridulating, a form of communication. Despite their initial aggression, the ants seemed less inclined to sting after a few days in the lab. Nevertheless, we managed to get some of them to sting through the parafilm, depositing their venom for further analysis.
Unfortunately, the initial attempts to extract usable venom were unsuccessful, leading us to dissect the ants to access their venom glands directly. This meticulous work involves carefully separating the ant’s abdomen to avoid rupturing the venom gland.
Under the microscope, the anatomy of a bullet ant is quite fascinating. The sting resembles a giant hypodermic needle, and the digestive system includes the crop, midgut, ileum, and rectum. The venom gland is located alongside these organs, and when opened, it releases an oil-like substance.
Studying bullet ants provides valuable insights into their biology and the chemistry of their venom. Despite the challenges, this research contributes to our understanding of these impressive insects. The Field Museum in Chicago supports this exploration, encouraging further discovery and education about the natural world.

– So the other group of ants that we have today are bullet ants.
– Why are they called bullet ants?
– Well, they’re called bullet ants because their sting is extremely painful, feeling akin to being shot by a gun.
– And you’ve experienced this firsthand?
– I have, just once, and I’d like to keep it that way. They are quite impressive ants; they are really large and fascinating.
– Are they the largest ant?
– They are one of the largest ants. There’s another genus called Dinoponera that can be larger, but their sting is not as painful.
– This is Paraponera. We’re studying the gut bacteria in this group of ants, but we’re also interested in the venom. I brought them back alive because at one point I tried to extract the venom, as we weren’t sure if we’d have permits to bring them back alive.
– You can just extract the venom. I can show you how I attempted to do it, but I’ll tell you that it didn’t work in the end. When I got the venom back, it was not usable. Let me grab my equipment.
– It’s not every day you get to extract venom from an ant at work.
– So this is our equipment. If you think about how venom is extracted from spiders, they usually bite something to release the venom, and it’s the same principle here. We have our empty tubes and a bit of parafilm, which is a waxy material that we can stretch across the top of this. We’re going to try to get them to sting through the tube and deposit their venom on the side of the tube.
– One thing I’ve noticed is that when you collect these bullet ants in the wild, they are incredibly aggressive. If you disturb them, they go into immediate attack mode. In fact, if you blow on them, you can hear them stridulate, which is a way of communicating. Now that they’ve been in the lab for a few days, they are almost docile. I’m curious to see if they’ll even sting through this.
– Yeah, see, this one is stridulating. Let’s see if we can get her to sting through.
– Oh! See that?
– So you see, she’s got her sting out. This is where I don’t want to lose control of her. She’ll try to sting through. Oh, there, you saw that sting go? That’s impressive.
– We will try to get another one to sting.
– Come on, ladies.
– She’s actually not as aggressive anymore. They seem to be thinking, “We want to hang out; we thought we were cool.”
– I know, that’s probably exactly what they think.
– Like, “Come on, I read your latest paper about the climatic regional distribution of my sister species.” I don’t even know if that makes sense.
– You don’t read all my scientific publications?
– I probably couldn’t get through the abstract. Not just yours, but most.
– I won’t take it personally. Oh, she’s got a very big sting, so let’s see if I can get her to—
– So that’s how you extract venom from a bullet ant. Essentially, we’re getting them to sting through this material, and they have now deposited their venom all over the top of this and inside the tube, which I can take back to an analytical lab to examine the chemistry within the venom.
– I’ve already mentioned that this didn’t work successfully, so we need to dissect out the venom gland, which is a bit trickier because they are large and quite active.
– Okay, so now we’re going to pull off her abdomen. These are some tough ants.
– Wow.
– Now we’ve got her body separated from her abdomen. I want to tease apart some parts of the abdomen to pull the venom gland out through the sting. I’ll start pulling apart the body, trying not to rupture the venom gland.
– This is meticulous work, dissecting ants.
– Yes.
– What is the smallest ant you’ll work on under a microscope?
– I’ll work on any size, even the ones that are so small you can’t see them on the labels.
– How do you even get forceps that small?
– It’s a challenge.
– Yeah, nothing like having to dissect on camera, too.
– So at one end, if you look through the microscope, you can see the sting hanging out.
– Oh yeah! It’s like a giant hypodermic needle.
– Yes. Starting at the other end, we can see parts of the digestive system. First, there’s the crop, which is the social food-sharing organ, then the midgut, the ileum, and finally the rectum, alongside which is where the venom gland sits.
– That’s amazing.
– Yes, it’s really fascinating. When you first open them up, you can see fat and trachea, and the contents within the gut can look clear, almost like water, or sometimes like waste. But within the venom sac, it’s almost like oil. When you burst it, it’s like oil coming out.
– Cool.
– Yes.
– Nice.
– So now the question is, are you going to hold a bullet ant for 10 seconds? The Brain Scoop is brought to you by the Field Museum in Chicago.
