Allomerus decemarticulatus

From Freepedia

Allomerus decemarticulatus is a species of ant that is notable for its tripartite symbiosis with its host plant and a fungus, which it uses to ambush much larger prey such as locusts.

Writing in Nature, entomologist Alain Dejean and coworkers describe how the ants take hair from the host plant (Hirtella physophora) and bind it together with a purpose-grown fungal mycelium (a complex of sooty mould species). They do this in order to make a galleried platform for trapping larger insects and thus supplement their intake of fixed nitrogen.

The ants immobilize their prey by hiding in holes in the platform, with their mandibles open, waiting for an insect to land. To trap the insect, the ants grasp any free appendage (legs, antennae, or wings) and moved in and out of the holes, thereby stretching the insect.
