The carnivorous stink bug Eocanthecona furcellata (Wolff.) is a polyphagous insect and is a potential biocontrol agent of several lepidopterous pests. The present study describes the predatory behaviour, the mechanism of feeding, intra-specific responses and cannibalism. The predators could withstand up to 72 h starvation and temperature upto 40°C. Females ingested more prey tissue than males. The efficient killing ability and polyphagy make E. furcellata a promising predator for biocontrol of lipidopterous larvae in -tropical and semi-tropical climates.
