Friend of the rice farmer: trichogrammatid wasp

Oligosita sp. is a trichogrammatid wasp. It is an egg parasitoid of leafhoppers and planthoppers. In the video, she locates a host egg by drumming the rice stem using her antennae. When an egg is located, she raises her body upwards while aiming the ovipositor to place one egg in one host egg.
