dragonfly rest on the plants. It has no response to my approach and close

next day morning. Its body is yellow in colour with black pattern. More

- T-mark Emerald
- Hemicordulia tau, Subfamily Corduliinae, body length 50mm
- The dragonfly's body is yellow in colour with black pattern. They look very similar to another Emerald species Australian
