The green-head ant (Rhytidoponera metallica) was the only ant other than Myrmecia species to cause anaphylaxis in patients. [257] Dogs are also at risk of death from Myrmecia ants; renal failure has been recorded in dogs experiencing mass envenomation, and one dog was euthanised due to its deteriorating health despite treatment.
