Here we have an excellent set of pic all shot by photographer Wynand Uys (Attribution CC licence) showing the dangerous work these south African Odontotermes termite workers must undertake when building new vents for their mound. Let's start with the pics and the description:

A general view of the situation, with still under construction vents (or maybe alate launching tubes) visible atop this small mound.


eee.jpg
Here we can see the workers buisy building with a fast-drying and robust "cement" made of soul, feces and salivary secretion. Note how there
are two types of workers: majors (bigger overall and with proportionally more robust heads) and minors (tiny and smaller-headed, and whose
main task is to care for the brood, soldiers and royals). Soldiers are present in Odontotermes but none is shown here.

But danger lurks around in the form of an aggressive ant species, the pugnacious ant (Anoplolepis custodiens). The ants don't assault the
building termities head on, but loiter and patrol around the construction works ready to grab and pull away workers that strayed too far from
the bulk of their companions. Here, two individual have captured a minor worker.

Still, even hunting workers is not fully exempt of risks, for despite not being very effective combatant their stout mandibles can still pack quite
powerful bites and be used for self-defence in a pinch. Here, a major worker retaliate against an attacker by clamping both of its antennae in its jaws.


To next post folks!

My impression is that ants are always the aggressors of the two animal types- true?

Very interesting why don’t the termites attack them on sight ? Do the ants sneak in like ninjas? :ninja:

Since termites are essentially herbivorous/humivorous (cannibalism within the colony to recycle nitrogen apart) they generally don't have particular reasons to attack ants as long as they are left undisturbed, tough i'm sure it could happen in situation where there is competition for the same resource (ex. a nesting site in a rotting log); meanwhile ants are mostly predators of other invertebrates.

These termites (even workers, tough soldiers are of course much more aggressive and effective) will bite if coming into contact of an ant, but don't really go out their way to attack them nor "rescuing" any nestmate that may had been pulled away, remaining fully focused on completing their construction as fast as possible: some casualties are inconsequential to the colony.

Thanks, that’s what I thought.
