We've lived in this house for 28-years but only now noticed this particular species of ant in our garden. They've suddenly infested a rock wall, moving rather fast all the time. I am seeking an ID so that I can know whether they are a pest of should just be left alone. Thanks for any help with this.

Agreed on F. sanguinea group, these are little slave making ants that raid other colonies nests to take their brood. They are very interesting to watch.
They are not pests, so you should leave them alone as they basically always stay outside and hardly ever come indoors, and when they do it’s mostly an accident.

If they are outside, then let them live in peace. Try to enjoy a super interesting species.

I have these in my backyard, the slaves do all the foraging for them so they stay underground until they need to raid again.

Other insects: Polistes sp. Queen

Ants I need: Pheidole sp., Trachymyrmex sp., Crematogaster cerasi , Dorymyrmex sp. Most wanted: ~~Pheidole morrisii~~

Raptiformica are awesome and some of my favorite ants. If you go outside at like 5-6 PM you could witness a raid, which is one of the coolest ant behaviors in north America.
