Dragonflies & Damselflies - Series III


Dragonflies and damselflies belong to the order Odonata. There are about 5,000 species of these creatures worldwide.

Studies of the fossilised dragonflies show that these creatures have not changed much form since the time it existed over 300 million years ago. Pre-historic dragonflies grow up to 30cm in length, with a wingspan of up to 75cm. Today's dragonflies with 18cm wingspan is a rarity.

These creatures have the ability to fly in reverse, an exclusive feature not seen on other insects. They are also able to hover in a fixed position in mid-air.

Dragonflies and damselflies are predators - as nymphs, they feed on aquatic creatures; as adults, they feed on air borne insects.

This stamp issue by Pos Malaysia features 10 different species of dragonflies and damselflies.
