Formica ravida & Polyergus breviceps
Sagehen Creek, California, USA
Mistaken identity? Formica ravida is a temporary social parasite of other species of Formica. Here a young queen has discovered a Polyergus nest, which she apparently perceived as a potential host Formica nest. Polyergus is a slave-raider that exists in mixed colonies with the same host Formica used by F. ravida, and it is possible that Polyergus' ability to fool its own host Formica extends to other species.
