[Note Guidelines] Photographer's Note
Well continuing the Swiss trek,This is the 4th image so far, with what is possibly the smallest insect I have yet posted. She is only 3-4mm high at the most. The crop from the original image is over 95%.
We were sat out side the other night my brother and I doing holiday things like enjoying a bier where we had eaten under the shade of a couple of fruit trees when this insect kept settling on the grey metal table we were sat at. It was so small I had to put glasses on to see it clearly at all.
It looked like a tiny May fly, so much smaller than the ones I have seen at home which are 10X the size at 3cm long with-out the fine tail hairs which can be more than twice that length. What attracted us was the tiny green ball which seemed out of all proportion to the rest of it. This it turns out is an egg capsule waiting for her to settle onto water for them to be released, I think she kept mistaking the grey metal of the table for water? I hope she found some water as after releasing the eggs she will die with her life's work complete.
The mayflies are part of an insect group known as the Ephemera which means short lived and can be as short as one day only. The do though have 2 stages of being an adult there is the just emerged one where they are known as Dunn's because the are dull coloured this is because the have a skin covered in hairs which shed water, and allows them to get airborne when emerging from the river. later this is shed and they become shinny and bright and sexually active, forming large clouds over water which dance up and down. the successful male grabs the female by the wings and copulates with her, finishing before they hit the surface.
The Ident as this particular one is tentative as there are 2000 different species, but this was the name that matched the image best IMO, so please tell me if I am wrong.
You will note the lack of speed and DOF, the light was failing fast and this was the best possible, Higher ISO,s give too much noise in the Sony for my liking.
Hope you like? Tomorrow we head for the moutain so maybe some real wildlife instead of what can be found in a Swiss garden ;0)))))#

Nice macro. A little bit underexposed... (I see in the note your explanation) I like the short DOF.

I have not seen this small either, very well seen and the eggs a great bonus, thanks for bringing it to us.

Robert, to me, unusual insect. It's beautiful and different.

A very composition with great details. Even with harsh cropping, the picture is still very good.

Very tiny Robert and therefor a good shot of it. The eggs sack is well shown and your notes are excellent. Good job!
