Abstract: The complex ecology and nutrition of “exploding” ants of the Colobopsis cylindrica group (COCY) is still poorly understood. Hitherto, this group of ants was thought to feed mainly on phylloplane biofilms with only scarce observations of carnivorous behaviour. This study focusses on observations and behavioural experiments conducted on Colobopsis badia and Colobopsis leonardi, two species native to Thailand. In experiments with C. leonardi, we investigated recognition and acceptance of diverse arthropod prey, as well as its mode of transport into the nest. In addition, preliminary data on C. badia were collected. We present the first recorded instances of predation for these species and discuss our findings in the light of previously published hypotheses on COCY nutrition and behaviour.
