Description of Ophionea nigrofasciata

Economic importance : Generalist predator
Hosts: Leaffolder larvae and planthoppers.
Description:
1. Ophionea nigrofasciata, known as the ground beetle is a reddish brown insect with a bluish band on the elytra.
2. Two white spots are located on both ends of the bluish band. The beetle has a shiny black head.
Biology and ecology
