Meat ant of the colony may deteriorate from overshadowing. Members of an affected meat ant colony later move to a nearby satellite nest that is placed in a suitable area, while invading banded sugar ants fill nest galleries up with a black resinous material. Meat ants sometimes attract cats because of the chemicals they secrete (dihydronepetalactone, isodihydronepetalactone and iridomyrmecin). Meat ants are generally intolerant of myrmecophiles (which are insects or other organisms that share positive interspecies associations with ants) living in their colonies, but "Cyclotorna" larvae are known to dwell in colonies. Although "Sphallomorpha" larvae sometimes prey on workers as discussed earlier,
Green-head ant out and forage to support their young. Another way colonies are formed is through budding, where a subset of the colony leaves the main colony for an alternative nest site. The green-head ant is known for its painful and venomous sting that can cause anaphylactic shock in sensitive humans. However, they can also be beneficial to humans, acting as a form of pest control by preying on agricultural pests such as beetles, moths and termites. The green-head ant was first described in 1858 by British entomologist Frederick Smith in his "Catalogue of Hymenopterous Insects in the Collection of the British
