Just barely a month ago I had a colony of slave making Formica pergandei raid a colony of either Formica pallidefulva, or F. incerta. I haven't studied up on either enough to tell them apart. Well the slave makers about a week later left the nest bare. They'd packed up all the slaves, all the brood, and all their colony members. I'm uncertain if this was a raiding party or the whole colony of F. pergandei. But anyhow you can read about that exploit here and see videos of them in the last third of Ant Chat Episode 22 (also available ad-free on iTunes).
Well to my surprise I went back to where the colony was and found another colony of Formica pallidefulva or incerta has moved on in.
Considering my native plant garden is loaded with caterpillars, the only thing really competing against the Formica colonies in the day (and Camponotus colonies at night) are wasps. Lots of pictures of caterpillars from my yard are featured here in an old post from last year, but here are some reposts from this year.
