''Daceton armigerum'' is a Neotropical species of arboreal ants, distributed throughout northern South America. ''D. armigerum'' combines several traits generally noted in some other arboreal ants i.e., populous colonies, large and/or polydomous nests, intra- and interspecific aggressiveness, trophobiosis, and capturing prey by spread-eagling them. ==Description== ''D. armigerum'' has a complex continuously polymorphic caste system, in which smaller workers nurse the brood and larger workers hunt, dismember prey items, and defend the nest.〔 The workers have trap-jaw, hypertrophied mandibles that snap together, triggered by sensory hairs situated on the labrum and powering a killer bite. The polymorphism of the worker caste is dramatic, and the size-frequency unimodal (monophasic allometry); foraging workers, themselves highly polymorphic, are larger than those from inside the colony. Workers are so well adapted to arboreal life that when they fall from the forest canopy they are able to glide down onto the trunk of their host tree.〔
