The Lemon-tipped Helicopter (Mecistogaster ornata) is a striking species of damselfly in the family Pseudostigmatidae, known as the "helicopter damselflies" due to their large size and slow, hovering flight. This species is particularly notable for its long, slender abdomen and distinctive lemon-yellow tips on its wings. Often perches with the body held nearly horizontal, typically on vegetation in shaded areas.
