Description:
Diacamma ceylonense is an Asian antspecies which shows high activity outside the nest. They need a high amount of proteins for their brood. Insects are paralysed and killed with their effective stinger. Humans often show local pain-reactions after they get stung by these ants. When they find a larger foodsource workers guide each other by tandemruns to the foodsource.
The genus Diacamma is often termed queenless. But correctly it has to be said that all newborn ants are ergatoid queens and become workers by amputation of their gemmae. These gemmae are special glands which enable the reproduction. After the old gamergate (Ergatoid) has died newborn workers are able to mate and start egg production.
