Hey everyone,

I've always found ants to be one of the most fascinating creatures on this planet, and while I was walking on a path the other day, I found these red ants moving back and forth along the path transporting their eggs. Just wondering if anyone can identify it and if someone could direct me to way to identify ants in my area on my own, that would be fantastic. I'm located in Calgary, Alberta, Canada and that is where this photo was taken.

Hi Steve,

Thanks so much for the great photo. I have to warn you that what I'm about to say might be so fascinating that it will make your mind explode. These ants are transporting pupae (homologous to the "coccoon" stage that caterpillars go through before they become butterflies or moths), but there's a good chance that it's not their pupae. Members of the genus Formica are tricky to identify, but I'm willing to bet that this one you observed belongs to one of the species that actually "enslaves" or "domesticates" closely related species of ants (such as members of the sanguinea group, like Formica aserva). The workers run into a nearby colony, and forceably remove the silk-encased pupae from the other species. When these pupal ants emerge as adults, they think they are in their home colony, but are actually unwitting servants to anther species! For an interesting discussion on what exactly the common name of this behavior should be ("domestication", "slave-rading", "piracy", etc.) check out this post by Alex Wild and this post by frequent AntBlog contributor James Trager.

Hope this helps!
best,

Just taking a break from the ant work now... Anyway, the field site we're at is beautiful and there's a good diversity of animals.

So far, the weather, diversity and learning so much about ants has been really amazing and I wouldn't exchange it for anything else!

While we here at Ant Course have been mostly obsessed with finding the fabulous local formicids, we are surrounded by other wildlife too. Here's a sampler:

And now, a few more ants we have seen at the Kibale forest during the ongoing Ant Course:

I am not a professional myrmecologist and have had no formal education in entomology, but after I obtained a copy of Hölldobler and Wilson's The Ants in 1994, an abiding interest in ants turned into a passion. Over the years I acquired a microscope, a camera for photographing ants, every ant book Amazon sells, a better microscope, better camera gear. I became a participant and eventually a moderator in the American ant enthusiast internet site, The Ant Farm and Myrmecology Forum (antfarm.yuku.com). I studied ants in the field while living in Europe and several American States, with further travel to Africa and the Middle East. I learned how to collect and preserve specimens, some of which found their way to university collections. But my skills are self-taught, and with no face-to-face interaction with real myrmecologists, I missed the benefit of professional feedback, advice, and direction. Reading books and papers has its limits.

Of course when I heard about Ant Course, I had to apply. Of course seats are limited and priority goes to university students and researchers who need the course for their work, so I didn't get in. So I applied again. And again. And again. After applying five times (or six?), I finally was accepted to attend this year's iteration in Kibale Forest, Uganda. So now I'm here, surrounded by real myrmecologists and students of myrmecology, with an opportunity to learn all the things that I could never learn from books, like how to actually pronounce all those crazy Latin and Greek names, such as clypeus, pygidium, Pachycondyla, Odontomachus, and Dolichoderinae!

Except it turns out no two myrmecologists pronounce these words the same way. O-dont-o-MOCK-us, o-dont-o-MAKE-us, to-MAH-to, to-MAY-to. Still, I am learning plenty of other skills I would never have figured out on my own, and I'm meeting some great people. Plus the ants here in Kibale Forest are amazingly diverse and endlessly fascinating. Here are a couple of photographs from the first few days in Uganda:

When I was younger I went to the local movie theater to see the film "Honey, I Shrunk the Kids". If you haven't seen this classic it is basically about a scientist who invents a shrink ray for some odd reason, his children along with the neighbor's children are accidently shrunken by said ray, adventure ensues, and a couple of the children unwillingly ride a bee. That's the basic formula and somehow this formula spawned several, though slightly less successful, sequels. Anyway, in the original film the now microscopic children are trekking through what could easily be mistaken for a remote tropical jungle but in fact it is their front yard that seems dangerous and inhospitable due to their very small stature. Along the way they befriend an ant, who they lovingly name "Anty", that serves not only as a form of transportation but also protection. Sadly the ant is killed protecting the children from a vicious scorpion. I would have said, "Spoiler Alert" before that last comment but if you haven't seen a 20 year old movie by now then the onus is on you. After seeing the movie I would pretend that I too had access to an ant large enough to ride into battle or one capable of chopping the heads off of my scorpion enemies or the occasional unsuspecting school bully. As I got older, movie ants came and went but I think it was with "Anty" that my fascination with ants began.

Besides being possible heavy artillery inspired by the fourth best Rick Moranis film or a method of exacting vengeance upon grade school tormentors, ants are interesting in other ways too. Ants are one of the most abundant life forms on earth and can be found on every continent except Antarctica. Ants represent nearly 10% of animal biomass in temperate regions and up to 15% in the tropics. Ants also occupy every forest strata from subterranean to arboreal. Just try to NOT find an ant. I dare you!

Today, there are over 12,000 described species with an estimated 12,000 more waiting for discovery or description. Some researchers even estimate the total number of ant species to be as high as 50,000 species! Whatever the exact number may be we already know that each species has its own unique natural history and even its own unique culture and way of life. Unfortunately, for many species very little is known.

Ants can be voracious predators of other arthropods or they can even grow their own food in the form of fungus gardens, which basically means that ants invented agriculture millions of years before humans. Some ant species form symbiotic relationships with other insects that feed on root systems and secrete a food substance called honeydew. The ants get a nutritious food source while their honeydew secreting companions gain protection and transportation to different roots. Ants are known to protect Acacia trees from harmful insects in exchange for proteinatious food substances called beltian bodies and small cavities in which to live in called domatia. Besides being great dispersers of seeds ants are also thought to overturn and enrich more soil than earthworms and changes in nest structure or native range can be used to study global climate change.

It's easy for us humans to overlook the absolute dominance of ant species as we tower above them or occasionally burn them with a magnifying glass. Sometimes humans think that we are masters of terra firma but in fact, ants have been here millions of years before us and will be here millions of years after we're gone. Yet, they have somehow remained so unpretentious about that fact. I for one would like to welcome our ant overlords.

Sunday morning, students and instructors arrived in Uganda. Several of us students visited the Botanic Garden and the Zoo. At the garden we got our first glimpse of the infamous Dorylus Driver Ants! The Ant Course introductory meeting was also held.

This photo is a close up of Driver Ants (known locally as Siafu). These few were just a small portion of the long and dense trail the ants formed as they crossed our path.

Tuesday the students were introduced to the subfamilies of ants, ant phylogeny and classification. In the afternoon, the instructors demonstrated various methods to collect ants. Some of the methods included using pitfall traps, Davis sifter, baiting using cookies or tuna, soil core samples, malaise traps, and the winkler system. In the evening Andy Suarez gave a talk about ant invasions and invasive ants. In this photo Peter Hawkes talks about sweep netting samples into emergence containers.

Wednesday we had a morning field trip to collect ants with our newfound knowledge of collection techniques and methods. Methods we practiced included winkler sampling, Hand/aspirator collecting, twig and rotten log collection, and several other methods. It was also too active of a day for only one photo. :) Enjoy a few! The first photo is a Trap-Jaw ant (Odontomachus) as it clasped to my pantleg and proceeded sting me through the fabric. It was a bit of a surprise, and then another worker stung me!

This photo shows me using a machete to loosen the litter for use in a winkler sample.

August is a seminal time for ant scientists. Every year for over a decade, 30 students and an assemblage of professional myrmecologists gather to learn about, and celebrate the diversity of, the world's most dominant insects. Part course, part mini-conference, part research expedition, the Ant Course has become a focal event for myrmecologists around the world.

2012 marks the course's first African installment. Some of the AntWeb team is now on site at Makerere University Field Station in Kibale National Park, Uganda, surrounded by monkeys, giant tropical trees, and a staggering diversity of insects. Wilderness isn't all the group is enjoying, however. Through the miracle of a cell phone modem, Ant Course finds itself with internet in the forest.

What does this connectivity mean?

For the first time ever we'll be blogging the Ant Course as it happens. Course participants will contribute observations, photographs, anecdotes, and updates from the field. Stay tuned to this space!

I bought the uncle Milton's ant farm for my son. We want to purchase some ants, but I don't want to have to replace them every few months. Do you have any suggestions for how to do this.

Thank you for your time.

Sincerely,
Melissa

Dear Melissa,

Good to hear you are already on your way to starting an ant farm! Luckily, colonies can last much longer than a few months, and we have had some very detailed posts on building and maintaining ant farms.

Please follow the instructions here, and here for a successful, long-living ant farm!

Good luck!

How far back does speculation go regarding the ancestry of ants? I have found that ants are thought to have come from wasps and I was wondering if speculation went further back to an ancestor for wasps etc. Is there a common ancestor that goes back to the sea?

Another question that I have is rather or not some wasps or wasp like creatures could have evolved from a line of ants, in other words the reverse of the theory that ants evolved from wasps?

Lastly, I am fascinated by ants that have an iridescent or blue hue and I found bees on-line that have an iridescent metallic green turquoise color. Is there an ant with a comparable appearance to this type of bee? Could these be related to the metallic bees? They look surprisingly alike.


Dear Pamela,

Ants and wasps are insects and are therefore members of the subphylum Hexapoda. Hexapods in turn belong to the phylum Arthropoda which includes crustaceans (crabs, lobsters, shrimp), myriapods (centipedes, millipedes), and chelicerates (spiders, scorpions, horseshoe crabs). All of these groups likely evolved from a shelled, aquatic ancestor. The evolution of land-dwelling behavior from aquatic ancestors appears to have occurred several times within this group. You should take a look at this study by Regier and colleagues and definitely check out Alex Wild's blog post discussing this paper.

Some of the strongest evidence that wasps are ancestral to ants and not the other way around is that the oldest known ant fossils are from about 100 million years ago, whereas the oldest known wasp fossils span back to around 150 million years ago. The changes in physical characteristics are also suggestive of a wasp to ant transition as an ancestral ant would mean that wasps had to reacquire wings and the ability to fly, rather than the far more likely loss of wings in ants. Lastly, phylogenetic analyses show that the ant clade (Formicidae) consistently nests within what we consider to be wasps, suggesting that ants are derived from a wasp-like ancestor (see this paper by Pilgrim and colleagues). All of this evidence taken together mean that it is far more likely that ants evolved from wasps than vice versa.

Ants and bees are related but every ant is more closely related to all other ants than they are to any bee. The same is true of bees in relation to ants. This means that the iridescent green color that is found in both ants and bees is a result of convergence to that character, not the close relationship of a particular pair of ant and bee species. In fact, there are many wasps that also have this type of coloration (see some of Alex Wild's beautiful photos here and here). These similarly colored species may use the same mechanisms for generating the necessary pigments, and these mechanisms may be present as a result of common ancestry but their expression is a result of convergent evolution.

Great questions!
