Leptogenys cyanicatena

In Cambodia, workers link their bodies in chains during the retrieval of freshly immobilized large millipedes (Peeters & De Greef 2015). Chains are a striking example of cooperation in ants, and this is the first report of a function during the transport of prey. In Thailand, 2-3 workers can retrieve shorter millipedes, and short chains have been observed when obstacles are encountered (Peeters & Mizuno unpublished)

Distribution based on type material
Thailand.

Biology
Highly specialised millipede hunters​. In Thailand, g​roups of 20-30 workers, ​recruited and ​led by one scout​, go out to subdue and retrieve single millipedes. Depending on the size of prey that needs to be dragged back to nest, they use chains or not.
