Mutillidae durable, the exoskeleton is also round, making it more difficult for predators to pierce it with attempted stings or bites. During all the trials that led to the fracture of a velvet ant’s exoskeleton, a total of 4 times, resulted in the death of that velvet ant within 24 hours. Thus aside from protection from predators, the exoskeleton provides a function maintaining moisture control. Male mutillids fly in search of females; after mating, the female enters a host insect nest, typically a ground-nesting bee or wasp burrow, and deposits one egg near each larva or pupa.

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
