Rice Bug (Leptocorisa sp.)

Leptocorisa sp. (rice bug) is a genus of true bugs in the family Alydidae, found widely across Asia and other tropical regions. These slender, elongated insects are usually brown to greenish and are commonly associated with rice fields. Both adults and nymphs feed on developing grains by piercing them with their needle-like mouthparts, which can cause empty or shriveled seeds, making them notable agricultural pests. While harmless to humans, they emit a strong odor when disturbed and play a significant role in the ecology of rice-growing areas as part of the food web.
