 "L. neglectus" was the first ant species to be observed performing "destructive disinfection" to their brood, wherein tending ants find pupae infected with "Metarhizium brunneum", a parasitic fungus.The tending ants then bite into the cuticle of the pupa and spray it with antiseptic poison to kill both the pupa and the fungus.While getting rid of the parasitic fungi, colonies are exposed to the "Metahizium" species.
