Allomerus decemarticulatus is a tiny tree-dwelling ant which lives in the forests of the northern Amazon. Researchers examining the relationship between different ant species and their host plants noticed that this particular ant lived on only one plant – Hirtella physophora – and that they built galleries hanging under its stems.
Many ant species build these galleries as hideouts to act as sanctuaries between their nests and foraging areas. But the team, led by Jérôme Orivel at the University of Toulouse, France, spotted that A. decemarticulatus were using these galleries as traps for prey.
