This was a smaller specimen (~20mm long). The colours are slightly brighter than the other specimen. This might be a male.
These are closely related to the Raft Spider (I had posted it long ago- Raft Spider repost - Indiawilds: Land of the Tiger. Conservation, Wildlife Photography, Communities (http://www.indiawilds.com/forums/showthread.php?t=1701)). Both are from the same family, Pisauridae, popularly known as "water spiders". They are found in the vicinity of fresh water, but may not necessarily have completely aquatic habits.

Canon 500D, Canon 100mm macro USM
Manual Exposure
Tv 1/200
Av 7.1
ISO 1600
Flash EC -1
Cropped. Didn't have any composition in mind, I clicked this only to record the abdomen pattern. I could have gone closer to avoid cropping, but this fellow was way too fast and ran off after a couple of shots.

Thanks, C&C welcome.

Abhishek,
You are fast turning out to be the "Spiderman" of IndiaWilds. :D

This image gives us a better idea about this species. Also, please check the right lower bottom where it is holding the leaf. Why didn't you try a narrow aperture? Thanks for sharing.

Cheers,
Sabyasachi

Thanks Sabyasachi,
Just before finding this spider I was clicking some small insects without the flash. Had set the Av to 7.1 to get a good shutter speed. Didn't get a chance to try narrower apertures on this spider since it ran off very soon. :(

Nice details. Liked the way it has placed its long legs on the leaves around to move fast. It surely stands out on the green leaves. Thanks for sharing the information. Look forward to more. Thanks for sharing.

Hi Abhishek

This is fabulous. Agree a narrower aperture would be good, but you were at ISO 1600 already and the SS wasn't very high, so this is still fine.

Thanks Bhargava,
To be honest, I could have used a narrower aperture... since I was using the flash, I would still have got a sharp image, even if the shutter speed was low. Guess this fellow was too fast for me :), will have to pay more attention before clicking next time.
By the way, forgot to mention- this was posted without any noise reduction. In fact practically straight from the RAW file.

Oh..didn't notice that you had used flash. By the way, canon's can be great high ISO performers when used without adding sharpness. :001_cool:

You can't add sharpness to an image after it is clicked.

Ah..sorry for that. I meant to say , when the sharpen tool is not used during processing :)
