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. We are rounding the bend with the ants series and there is no better way to do that than to take to the sky. The title of this episode is Arboreal Ants. There are ants that live in trees and never touch terrestrial earth their entire lives. You thought the Leafcutter ants were amazing, well hold on to your hat because the seventh thing I like about ants is the colonies that live in the trees. Arboreal ants, which are ants that live in trees, are found on many different continents and there is more than one species, but we are going to focus on one species in particular so we can really see their amazing qualities in detail. We’re spending some time with the Weaver ants of Africa, Oecophylla longinoda. Now living in a tree for an ant is no small feat, so how do they do it? Terrestrial ants dig into the dirt and create many chambered nests. It’s kind of difficult to dig into  a tree, so where are arboreal ants living? Weaver ant nests are most common in the outer, uppermost branches of trees where the sun light is bright. Here, the ants will bind adjacent healthy leaves together to create a treetop tent. The size of each nest will vary but is often between the size of baseball or a volleyball. They are as light as an inflated ballon and can withstand wind, rain, and enemy invasions. To begin building a nest, a worker ant will pull the edge of a leaf toward the edge of another leaf. If her bending is successful other workers will come to her aide.  Now weaver ants get their name from the next step. To keep the leaves together they employ their larvae. If you’re think, “What?” I hear ya! The larvae are picked up by workers and taken to the edge of the leaf connection. The workers tap the larvae on the leaf to encourage the larvae to release silk. Yes, the larvae of many species of ants create silk. The Weaver ants use this silk to secure the leaves together. The motion of shuttling the larvae back and forth to connect the leaves with the silk is where the weaving comes in. The nests may last for years because when one leaf dies the ants will just weave in another living one.  The nests are larger enough to house thousands of ants, but the weaver ants don’t have just one nest in the tree. They travel all over the tree that they call home, so they often build other trees  op tents so they can maximize their resources. They don’t stick to one central nest, they have the ability to move around when they need to. One territory can have multiple nests. The queen is often in a nest that is the most centralized to the territory, but her eggs are distributed throughout all the nests. With all of these spread out workers, Weaver ants have to have an excellent communication strategy. And boy, do they! Earlier we learned that pheromones are integral to ant communication. It’s the same with weaver ants, but they have a specialized gland that helps the pheromones that they use to create their paths last longer than terrestrial ants. They have an anal gland that helps them make their poop a bit more than just poop. To keep their pathways from wearing away t
