Larvae of ant-lion Myrmeleon brasiliensis (Navas, 1914) go through three instars before the formation of pupa.
Probably if the prey size varies positively with size ant-lion larvae, the number of attacks at the preys would not vary between different instars of M.
In the field, the capture rate of ant-lion larvae is quite reduced (Heinrich and Heinrich 1984) and, since smaller larvae do not manage to efficiently seize their prey in the first attack, they start suffering from inanition.
On seizing the prey at the abdomen, ant-lion larvae shake them to break their exoskeleton and then release digestive enzymes (Devetak 2005).
