The green-head ant (Rhytidoponera metallica) was the only ant other than Myrmecia species to cause anaphylaxis in patients.

Myrmicinae is a subfamily of ants, with about 140 extant genera; [1] their distribution is cosmopolitan. The pupae lack cocoons. Some species retain a functional sting. The petioles of Myrmicinae consist of two nodes. The nests are permanent and in soil, rotting wood, under stones, or in trees. [2]
