Myrmecia (ant) encountered before. Based on five species, the median lethal dose (LD) is 0.18–0.35 mg/kg, making it among the most toxic venoms in the insect world. The toxicity of the venom may have evolved due to the intense predation by animals and birds during the day, since "Myrmecia" is primarily diurnal. In Tasmania, 2–3% of the human population is allergic to "M. pilosula" venom. In comparison, only 1.6% people are allergic to the venom of the western honeybee ("Apis mellifera"), and 0.6% to the venom of the European wasp ("Vespula germanica"). In a 2011 Australian ant-venom allergy study, the objective of
Meat ant The meat ant was first described in 1858 by British entomologist Frederick Smith in his "Catalogue of Hymenopterous Insects in the Collection of the British Museum part VI", under the binomial name "Formica purpurea" from a holotype worker ant he collected in Melbourne, Victoria. The type material is currently housed in the Natural History Museum, London. In 1862, Austrian entomologist Gustav Mayr erected the genus "Iridomyrmex", and reclassified the meat ant as a member of "Iridomyrmex" rather than the genus "Formica". The ant was named "Iridomyrmex purpurea" in 1862. Mayr renamed the ant as "Iridomyrmex purpureus" one year after. "I.
