Philidris Shattuck, 1992

 Overview  Images  Identification  Specimens --- References/Links  Nomenclature  Reports 
Species of Philidris form large nests containing many thousands of workers in cavities of living plants or in rotten wood above the ground.  Some species are associated with plants which have special swollen stems in which the ants nest (these plants are called myrmecophytes, and include the genera Myrmecodia and Hydnophytum).  Philidris workers are very aggressive when disturbed and will swarm in large numbers to attack intruders.  Many species are also polymorphic, with workers varying greatly in size and with some having enlarged heads.  These large-headed workers are equipped with powerful jaws which they use while excavating nests in tough plant tissues and rotten wood.
