this is actually two observations on the same date at slightly different locations in the park but appear to be the same species to me. I saw one at the first location and took the individual picture of it but then a little further down the trail I saw a very active group some with wings, some without, many looking like this one, some were different.

aka Acrobat ants. Photos are not the same individual, but 5 ants along their path. For several years now they've been going along the top of the fence and up the side of the garage. The fence has trumpet vine with aphids/honeydew.

A pretty big ant of about 2cm in length. So amazing to see the worker ant carrying the luggage bigger than its own size.

I have photographed this ant colony a number of times, but didn't feel that I had a satisfactory closeup for a positive id. But this time I can see the jaws in one photo.

These ants move at a measured pace not like other nearby ants that move very rapidly. I thought that all adult ants of a colony were the same size, but one of the ants here was noticeably smaller (see third photo) but appears to be the same species, and disappeared into the same nest entrance as the rest.

They were busily gathering bite sized morsels from a discarded orange coloured waffle icecream cone.

The colony was inside/behind a concrete or brick block wall joined with cement mortar holding up a sandy bank.

This second colony behaves a little differently from 1038228. They move very rapidly, and every so often bend double and mark objects? with their abdomen. They also appear to have fewer serrations on their jaw, and a lot have a lighter coloured area where the abdomen joins the next body segment.
