[Note Guidelines] Photographer's Note
Flies in the Diptera family Syrphidae are commonly known as hoverflies, flower flies, or Syrphid flies.

As their common names suggest, they are often seen hovering or nectaring at flowers; the adults feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In some species, the larvae are saprotrophs, eating decaying plant and animal matter in the soil or in ponds and streams. In other species, the larvae are insectivores and prey on aphids, thrips, and other plant-sucking insects. Aphids alone cause tens of millions of dollars of damage to crops worldwide every year, and so aphid-feeding hover-flies are being recognised as important natural enemies of pests, and potential agents for use in biological control. Adult syrphid flies are important pollinators.

Many Syrphids mimic bees or wasps in appearance. It is thought that this mimicry protects hover flies from falling prey to birds and other insectivores which avoid eating true wasps because of their sting. However a flower fly and a wasp can be distinguished by counting the wings: the flies have two wings, and the wasps and bees have four. They can also be distinguished by simply looking at the head: if it looks like a fly's head, then it is likely a fly. Hover flies get their name from their characteristic flight pattern of hovering nearly still, then darting a short distance very rapidly only to start hovering again, a pattern not seen in the wasps and bees they mimic.

The shot was captured with the camera supported on the tripod used with just one leg extended. The Raynox necessitates the narrowest aperture setting to render an acceptable DOF hence the use of the fill flash to increase shutter speed.

Hello Mark,
A great close-up of this insesct.
Very interesting the POV used, wich show us a different pose.
I like specially the big, shining and red eye, and all sharp details captured by your lens.
Good composition and presentation, the frame stands up the best of the picture.
Congratulations and thanks for share,
JM

A fine macro of this hoverfly, Mark. Your camera settings along with a judicious use of fill-flash have resulted into a high quality capture with sharp focus, minute details and perfectly natural colours. The half moon of the compound eye visible from this perspective is without blemish.
Well done.
Ram
