Description

Hope I've got this ID right, I don't know anything about ants, but the giant spines on the thorax seem pretty distinct. Maybe 7 mm tops.

This looks like a good ID. With the color, number of antenna parts, spikes, and how the body looks from the side, this looks like M. andrei. It is easily confused with genus Pogonomyrmex, but I don't think so this time.

Were there signs of harvesting of seeds?

Yup, I definitely saw them carrying seeds around. Does Pogonomyrmex not carry seeds?

Just wondering: did you notice any interaction between the crickets in the second picture and the ants? I know some ants tolerate crickets in their colonies because the crickets groom the worker ants.

They seemed a bit jumpy when they touched each other, but other than that no, didn't see any grooming or feeding or anything like that.

Pogonomyrmex and Messor are both harvesters.
