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
Jack jumper ant southern states of Australia, due to a high proportion of the population having significant allergies to the ant's sting. The ant is a significant cause of major insect allergies, responsible for most anaphylaxis cases in Australia, and rates of anaphylaxis are twice those of honeybee stings. One in three million annually die of general anaphalaxis in Australia alone. Over 90% of Australian ant venom allergies have been caused by the jack jumper. The ant is notorious in Tasmania, where most fatalities have been recorded. In 2005, over a quarter of all jack jumper sting incidents were sustained in Tasmania; excessive
