Pheidologeton diversus
''Pheidologeton diversus'', common name East Indian harvesting ant, is a species of marauder ant widely distributed throughout Asia.〔(Japanese Ant Database Group )〕〔(myrmecos.net: ''Pheidologeton'' (marauder ants) )〕〔(The Ants of Africa: ''Pheidologeton diversus'' (Jerdon) )〕
==Description==
''P. diversus'' is a eusocial insect and individuals have continuous allometric variation in size and morphology to facilitate task allocation and partitioning of work. Minor workers are between 1.3 and 2.5 mm in length, but major workers are much larger. Between the smallest minor and largest major workers there are many intermediate forms. The largest workers can have heads approximately 10 times larger than that of their smallest counterparts. The dry weight of a large major worker can be approximately 500 times heavier that of their smallest counterparts. These size-related morphological differences correspond with their division of labor. For example, small, young, minor workers specialize in caring for the larvae but extend their activities as they grow older.〔
Minor workers have yellowish brown to reddish brown bodies. Their mandibles each have five "teeth" and their antennal scapes are short and do not exceed the posterior margin of the head. Minor workers have rectangular heads with weakly convex posterior margins in full face view〔
Major workers have reddish brown to blackish brown bodies. Their heads are proportionately larger and almost square with convex posterior margin in frontal view. Mandibles of major workers are large and triangular, with an acute apical "tooth". Their masticatory margins lack distinct "teeth". Their eyes are relatively small and their antennal scapes are half as long as their heads.〔
