An ant mill is an observed phenomenon in which a group of army ants, which are blind, are separated from the main foraging party, lose the pheromone track and begin to follow one another, forming a continuously rotating circle. The ants will eventually die of exhaustion. It has been reproduced in laboratories and has been produced in ant colony simulations. The phenomenon is a side effect of the self-organizing structure of ant colonies. Each ant follows the ant in front of it, and which works until something goes wrong, and an ant mill forms. An ant mill was first described by William Beebe in 1921 who observed a mill 1200 ft in circumference. It took each ant 2.5 h to make one revolution. Similar phenomena have been noted in processionary caterpillars and fish.
Ants are eusocial insects of the family Formicidae /fɔːrˈmɪsᵻdiː/ and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from wasp-like ancestors in the mid-Cretaceous period between 110 and 130 million years ago and diversified after the rise of flowering plants. More than 12,500 of an estimated total of 22,000 species have been classified. They are easily identified by their elbowed antennae and the distinctive node-like structure that forms their slender waists.
Ants form colonies that range in size from a few dozen predatory individuals living in small natural cavities to highly organised colonies that may occupy large territories and consist of millions of individuals. Larger colonies consist mostly of sterile, wingless females forming castes of "workers", "soldiers", or other specialised groups. Nearly all ant colonies also have some fertile males called "drones" and one or more fertile females called "queens". The colonies are described as superorganisms because the ants appear to operate as a unified entity, collectively working together to support the colony.

Nat Geo Wild (stylized as Nat Geo WILD or abbreviated as NGW) is a cable/satellite TV channel focused primarily on wildlife and natural history programming. It is a sister network to National Geographic Channel and it is the latest channel to be jointly launched by the National Geographic Society and Fox Cable Networks.
It first launched in Hong Kong on January 1, 2006. The channel later launched in the United Kingdom, Turkey, Ireland, Romania, India, Vietnam, and Poland replacing the now defunct Adventure One. The channel remains the world's first bilingual wildlife service, available in English and Cantonese in the Hong Kong market as well as Tagalog in The Philippines. The channel launched in Latin America on November 1, 2009 as a high definition channel. In 2010, it launched in the United States.
As of February 2015, approximately 57,891,000 American households (49.7% of households with television) receive Nat Geo Wild.
The channel launched in South Africa in mid-2009, and is available on the South African Satellite Network DSTV.

Ants of various species can be seen in Costa Rica streaming through the jungle in huge numbers. They can do this by producing pheromones that act as a guide for moving enormous numbers of ants to a specific destination. Basically, they smell the ant in front of them. Very rarely a group of ants gets lost from the main group and they end up following each other in a circle. Eventually they die from exhaustion. You can see the dead ones piling up in the middle. The moral is- pick your leaders carefully.

Ants secrete a pheromone called Trail pheromones so it can lead members of its own species toward a food source. Like a cube of Borg drones that's been separated from the collective, these army ants were somehow separated from the main foraging party and they lost the pheromone trail and began to follow one another, forming a continuously rotating circle. The ants that are stuck in the "antnado" will usually die of exhaustion. Luckily for these ants, they only swirled for about half hour and then another half hour later, not an ant could be seen. It's a real-life Antnado! (yes, I'm claiming to be the first one to coin the name).
The ant mill was observed on a Colombian birding trip in February 2015.

On Christmas day my niece sent me the curious gift of an gel Ant Farm. I was surprised to learn Harvester Ants are common for ant farms as I was mostly familiar of them as having painful bites for their size (12 ants biting/stinging can kill a rat, and that they have a rating of 3 on the 0-4 Schmidt Pain Index which puts them above even fire ants, honey bee stings, yellow jackets, and other insects I thought were pretty painful) Because of the length of time there are bound to be errors with this kind of time lapse process inside a home. One of the cats had a spat with the dogs that knocked the tripod around slightly once. A few times you can see flashes of cat through the video. This is unedited footage to preserve its scientific integrity and to sustain my lazyness. Today on day 52...

I'm back at the Ant Village for another season, working to build my own Permaculture based homestead, as well as realize my vision for the Permaculture Bike Park. Follow along as I attempt to create my dream out of the tree, rocks, sand, and soil of my one acre plot, at Wheaton Labs in Western Montana. I spent most of this week working up at the neighbors', who are building several cabins so veterans can have a quiet place to stay and unwind. I still managed to get some work done at my own plot, gathering logs and milling them into boards with my chainsaw mill. In this video I share more about how I set up the mill and make cuts. A summer heat wave moved in, bringing with it a change in the scenery around my plot. I give a short tour of the different plants and flowers showing up arou...

Back in the early 2000's I picked up a $15 flea market "over the shoulder" RCA camcorder (with a tube type imager no less) and made a very primitive movie of the melt shop at the steel mill where I worked. Now it's worth noting that it was verboten. I did an edit (very primitive "music video") and ended up distributing almost 500 copies of the darned thing. EVERYBODY at the mill wanted one (rolling mill and meltshop). In fact there's a platemill movie I'll post when I find it. At any rate, it was like I was doing a drug deal: I had copies of the movie on the inside pocked of my flame retardant jacket and people would walk up to me and hand me $2 and I'd give them a copy of the movie surreptitiously. What a hoot. So go easy on me in the comments. I'd never ever made a movie and this...
