leaf-cutting ants

Landscape

While in Presidencia Roque Saenz Peña in the Chaco Province of Argentina (on our way to Salta) we came across this sighting. I wonder if you can guess what it is?

It looks like some kind of terraces that could be of volcanic origin?

Not so. It is a finding I have not seen before: ant nests!

They “sprouted” in the front of our hotel and their builders were some species of leaf-cutting ants busy carrying stuff to their nests. However, this cargo was not the usual green bits but yellow.

Here they are in motion…

Curious, we followed the yellow ribbons for quite a long distance around the corner and immediately saw the “victim” about 50m away: a smallish tree still covered with yellow flowers despite the ongoing harvest.

I am sure that in a couple of days the ants will have to look for other source of sustenance as the flowers would have gone!
