Summary: How do ants organize all those colony residents? Join Kiersten to find out the amazing answer to this question.   For my hearing impaired followers, a complete transcript of this podcast follows the show notes on Podbean   Show Notes:  “Tales from the Ant World” by Edward O.

(Piano music stops)   Kiersten - Welcome to Ten Things I Like About… I’m Kiersten, your host, and this is a podcast about misunderstood or unknown creatures in nature. Some we’ll find right out side our doors and some are continents away but all are fascinating.  This podcast will focus ten, ten minute episodes on different animals and their amazing characteristics. Please join me on this extraordinary journey, you won’t regret it. I feel like we have already talked about so much cool stuff about ants and we are only on episode three. This is going to be quite an exciting series on ants. The third thing I like about ants is how they communicate. Most of us have probably seen a line of ants moving from one place to another at some point in our lives. We may have stopped to take a look and wonder what they were doing or just walked on by without too much of a second thought.  Either way, your brain probably took a moment to puzzle over what they were doing, where they were going, or how they knew where to go.   Communication is the key! So, how do ants communicate? Two types of chemical substances lead ants through their lives. Pheromones which are chemical substances passed back and forth between individuals of the same species and allomones which are chemical substance used by other species and used by social invertebrates to hunt prey or avoid being prey. A quote from Edward O. Wilson about ant communication states, “Among all of the organisms that live by smell and taste, ants are the virtuoso of chemical communication.” End quote. Just a heads up, of you haven’t already figured this out, I will be quoting E.O. Wilson a lot in this series, but he’s learned so much about ants and he is always eager to share that I just can’t help myself. Ants have created a unique chemosensory world that no other creature known to humans can surpass.  Let’s look first at how those ants traveling in a line know exactly where to go? When an ant colony needs resources they send out scouts to find what they need. When a scout finds what they want, they eat or drink their fill and run back to the nest in as straight a line as possible. The scout always knows where her nest is regardless of how far away they have traveled (we will discuss this in a moment). When she arrives at the nest, the scout will puke all over the floor. No serious, she will gurp up a small portion of what she ingested in front of a few ants and then turn around an head back. Some of her sisters will immediately follow her out. But why? She just came in the house threw up all over the floor and then left! What is going on?  When that scout regurgitated the resource she found she created a pheromone that simply stated, “I’ve found what we need! Here it is! Follow my trail to find more!” Who can resist an invitation like that? The original scout laid a scent trail for herself by dragging her stinger along the ground to follow back to the resource and now her fellow workers will also follow that trail to help gather more of what they want. E.O. Wilson encourages you to experiment with some sugar water to see this phenomenon for yourself. You can use a drop of sugar water near a line of ants and watch what happens when they find it! Please use common sense if you choose to do this. Be careful to keep yourself and the ants safe from harm. How do ants identify these chemical signals? Do they have a nose to sniff them out? Sort of. They do not have a nose like a mammal that sticks out on the
