Butterfly or dragonfly?
See them at Brides Pool Road, or at Hong Kong Wetland Park. This large insect flies slowly, often quite low to the ground and has two pairs of butterfly-like wings, but a body like a dragonfly. And yes, it is a dragonfly called the "Variegated Flutterer", and each individual has unique patterning on its wings.
Insects are a class of invertebrates that have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. The word "insect" comes from the Latin word insectum, meaning "with a notched or divided body".
Insects are incredibly diverse, with the number of extant species estimated at between six and ten million.
They represent a staggering 90% of the differing animal life forms on Earth.
