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
Ant on a rubber rope a given time formula_36 is its speed relative to the rope, i.e. formula_18, plus the speed of the rope at the point where the ant is. The target-point moves with speed formula_38, so at time formula_39 it is at formula_40. Other points along the rope move with proportional speed, so at time formula_39 the point on the rope at formula_42 is moving with speed formula_43. So if we write the position of the ant at time formula_39 as formula_45, and the speed of the ant at time formula_39 as formula_47, we can write: This is a first order linear differential
