Pit Building and Prey Seize
Antlion larvae are famend for establishing conical pits in sandy or free soil. These pits function traps for unsuspecting ants. When an ant ventures too near the sting of the pit, the unstable sand causes it to slip all the way down to the underside, the place the antlion larva lies in wait. The larva then makes use of its sturdy mandibles to grab the ant, stopping escape. This pit-building and ambush habits illustrates a specialised adaptation for capturing ants.
-
Digestive Course of
As soon as an ant is captured, the antlion larva injects digestive enzymes into its physique, liquefying its inner tissues. The larva then sucks out the ensuing fluid, consuming the ant’s inner contents. After extracting all usable vitamins, the antlion larva discards the exoskeleton, usually flinging it out of the pit. This environment friendly digestive course of permits the larva to acquire most dietary worth from every captured ant.
