Jumper Ant

There's a nest of these large and very aggressive ants living in our backyard. Theirs is a corner of the garden I prefer to avoid (I was bitten there a couple of months ago - the pain was crazy!!) but they will roam far and wide so we encounter them everywhere in the yard, and they like to forage on plants. Apparently they like to jump (hence the common name) but I haven't seen this myself.
