Photographer's Note

I took my camera out for a test run with some new equipment I just picked up; the Canon EF 100mm f/2.8 Macro USM and the Macro Ring lite MR-14EX (a flash that attaches onto the end of the lens).
I took a walk down to the Singapore Botanical Gardens in hopes of finding some insects to photograph. It took a little while to find a good spot- but eventually found a spot.

I've tried to find out what type of Dragonfly this is, but had no luck. I did however dig up some information on Dragonflys...

A dragonfly is characterized by large multifaceted eyes, two pairs of strong transparent wings, and an elongated body.

Dragonflies typically eat mosquitoes, midges and other small insects like flies, bees, and butterflies. They are usually found around lakes, ponds, streams, and wetlands because their larvae, known as "nymphs", are aquatic. Dragonflies do not bite or sting humans; in fact, they are valued as a predator that helps control the populations of harmful insects, such as mosquitoes.

The life cycle of the dragonfly, from egg to death of adult, varies from six months to as much as six or seven years. Female dragonflies lay eggs in or near water, often in or on floating or emergent plants. Most of the life cycle is spent in the larval (nymph) form, beneath the water surface, using internal gills to breathe, and catching other invertebrates or even vertebrates such as tadpoles and fish. In the adult (flying) stage, larger species of dragonfly can live as long as four months.

Dragonflies have very good eyesight due to their unique eye structure. Dragonflies have up to 30,000 facets to their compound eyes; each one is a separate light-sensing organ or ommatidium, arranged to give nearly a 360ー field of vision.

I hope you like it!
