Description

Cyrtorhinus lividipennis is a light green mirid bug with green membranous wings and black spotted thorax. It is elongate and oval. The second antennal segment is slightly longer than the width of the pronotal base. The tip of the first antennal segment is greenish yellow. It has green legs except for the yellowish tibiae.

Biology and ecology

Cyrtorhinus lividipennis is a plant-feeding insect. It is also predaceous on planthopper and leafhopper eggs and young nymphs. It lays its eggs inside plant tissue. A female mirid bug can produce 10 to 20 individuals. Development from egg to adult takes 2 to 3 weeks.

Each predator preys on 7 to 10 eggs or 1 to 5 hoppers daily. Both the adults and nymphs suck the hopper eggs by inserting their mouth parts and collecting the egg liquid, causing the eggs to collapse.
