[Note Guidelines] Photographer's Note
Dolichopodidae, the long-legged flies, make up a large family of true flies with more than 7,000 described species in about 230 genera distributed worldwide. The genus Dolichopus is the most speciose, with some 600 species. They are generally fairly small, metallic flies with large, prominent eyes but otherwise they show considerable variation: most have long legs but some do not. The males often have enlarged genitalia which can be useful for species recognition. The adults are predatory on other small animals.

This family includes the subfamily Microphorinae, formerly placed in Empididae, and briefly considered a separate family[

Ecology and behaviour

Dolichopodidae give visual (as opposed to chemical or other) signals during courtship; many studies have been undertaken of this fascinating behavior. The larvae occupy a wide range of habitats, both terrestrial and aquatic, and can be predators or scavengers.

Evolution and systematics

Dolichopodids are well represented in amber deposits throughout the world and the group has clearly been well distributed since the Cretaceous at the latest. Together with the Empididae they are the most advanced members of the Empidoidea. They represent the bulk of Empidoidea diversity, containing more than two-thirds of the known species in their superfamily.

Internal relationships of the Dolichopodidae and their delimitation versus the Empididae are not yet resolved to satisfaction. It is likely that the considerable number of subfamilies is subject to change.

Hello Al
This is a super sharp image of your fly - it looks so sharp and delicate - amazing colours too.
I am very impressed with this
Well done
Janice

Hallo Al
I have been absent from the site for a while and missed some lovely postings. I am glad to lay my eyes on some great images, this one of yours being one.. This is indeed a excellent macro of this long legged fly. The details and colours is amazing not to mention the focus, sharpness and composition. This is a 1st class image with lots of details to appreciate. I have tried my hand to something similar to this but have not yet been successful. In total this is a very pleasing and well presented image and I hope to see more of these quality shots in the future. Thanks for sharing. I’ll also be back soon with my 50th posting.
Best regards.

This is a striking capture of this almost microscopic Long-legged Fly, AC. The sharpness on the main parts of the subject's body is phenomenally sharp. The metallic colours are wonderfully recorded without least exaggeration.
What equipment do you use for macro photography? I would suggest you update your equipment profile. It is always educative to know what equipment a gifted photographer has used in making a picture of this high quality.
BTW, I also shot and posted a picture of this fly some time back.
Thanks and regards.
Ram

An other good job...
