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
Longhorn crazy ant genetic clones and her sons are the genetic clones of her mate. The male and female gene pools thus remain completely separate (assuming workers never reproduce) and this has allowed the longhorn crazy ant to become one of the most widespread invasive species in the tropics. The process is known as double cloning and was discovered by evolutionary biologist Morgan Pearcy of the Université Libre de Bruxelles. SC Longhorn crazy ant The longhorn crazy ant ("Paratrechina longicornis"), also known as "black crazy ant", is a species of small dark-coloured insect in the family Formicidae. These ants are commonly called "crazy
