It all began when two termites fell in love.

Were it not for the terraforming termites, the Okavango Delta of Botswana would be a barren flat floodplain in the Kalahari desert, much like the Black Rock Desert.

The termite mounds tower up above the seasonal floodplain, up to 30 ft. tall in some cases, and provide a base for bushes and trees that need to be above water to germinate. And that supports the larger animals, like the Fisher Eagle seen here.

The landscape is literally transformed by termites.

After a mature colony dies, the inner chambers provide birthing dens for jackal, hyena and wild dog that dig out caves to raise their pups.

As with the other social insects, the termite behavior at the colony level is just fascinating. They farm a fungus underground, and their crop needs a constant temperature of 87 degrees. While outside temperatures can fluctuate between 35 degrees during the night and 104 degrees during the day, the thermoregulation of the mound keeps the temperature in a 2-degree band. Hot air rises in the vertical column drawing cooler air in from below, regulated by continual termite tending to air vent opening and closing. Wind also induces airflow rhythms similar to the breaths of a cow. No single termite has enough neurons to build or manage such a complex system.

It reminded me of a SFI talk on another social insect:
“Bee hives must stay at 96 degrees for the bees to reach maturity. Bees can cool with their wings or huddle together for warmth. Genetically homogenous bees all move together, and the temperature fluctuates widely. Genetically diverse bees keep the hive at a constant temperature.”

The program does not reside in the individual.

  1. A really cool mound in Mombo camp
    IMG_5010And an interesting comparison from SFI as wellTermites and Towerstermite diagram

  2. The weather conditions are almost identical to Washington DC in the summer…(daytime temperatures)….

  3. Fascinating thoughts…but too deep for me…
    I think with bugs, its all done with pheromones…genetics,and instinct.
    Like building 6 sided egg chambers,etc.

    Interesting to see that Termites are designing cathedrals…
    When they start writing books I will be even more impressed.

  4. Yep, it takes two termites to dance tango:D and how many to biuld this marvel??? Also, maybe these were rockets, pyramids or Gothic cathedrals…inspiring creatures…great find! Love learning new things here, thank you:)

  5. Googling termites bring you mostly websites on termite infestation (not expressed admiration for their amazing architectural marvels), they can destroy a house in 2-3 years… ouch, they are also great recyclers and I found even one termite love song:D http://www.youtube.com/watch?v=Mc6ZexAW6GU
    Wonder if humans could use their creative abilities and make termites mini-bio-robots…

  6. Cool one – take the army of nano-robo-termites on Mars and let them build it:D

  7. Just accidently found this – posted yesterday: Obama’s 50th birthday celebration – they used Steve’s portrait in Chicago! – it is a very small world:

  9. Haha so cool =) First time I see the termite one. Merci Steve =)

  10. wow… I am going to leave strake_davis1’s spam here because it is a new level of customized social spam that seems to go beyond the normal fare (that I delete). I’m guessing they have crowdsourced an army of people to come up with stealth spam like this. The reference to "pretty cool structures" is clearly processing the content of this page in a way that a bot could not… quite yet…. I think… =) Hmmm…

    Strake: are you human? A simple yea/nay would pass this Turing Test…
