Rice Ear Bug

Typically found in rice fields, grasslands, and areas with dense herbaceous vegetation throughout South and Southeast Asia.

It is a herbivore that feeds primarily on the sap of developing rice grains during the milk stage, as well as various other grasses.

Adults are active during the early morning and late afternoon. They lay eggs in rows on leaf blades and undergo incomplete metamorphosis. They are known for emitting a strong, foul odor when disturbed.

This insect is a major agricultural pest that can cause significant yield loss in rice crops by causing grains to shrivel or blacken. It poses no direct physical risk to humans but can be a nuisance due to its smell.
