Writing in Nature, entomologist Alain Dejean and coworkers describe how A. decemarticulatus takes hair from its host (the Amazonian ant plant) and binds 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. The ants do this in order to supplement their intake of fixed nitrogen. Nature is one of the oldest and most reputable general-purpose scientific journals, first published on November 4, 1869. ... Hair is the filamentous outgrowth of the epidermis found in mammals. ...
