The VARIAGATED FLUTTERER.
A cool name for a cool insect.....this stunning creature is a Variegated Flutterer. Its forewings and hindwings have a distinct - and unique - pattern of black and yellow and they are quite unmistakable in their flight as they fly more like a butterfly than a dragonfly, flying slowly, often quite low to the ground.
This picture shows how they use their wings for their distinctive flight pattern.
As mentioned, each individual has a unique patterning on its wings, meaning you can track individuals, like they do with whale-sharks. But above the water. Maybe without a snorkel.
