Fly foot

Post by Oscar_macro »

This is the first photo that I share in the forum, I have learned a lot here, so now that the photos come out half well, I think it is a good place to share it.
I am not sure which specimen is this, a friend left it for me to take photos of it, it is a kind of large and very dark fly, with golden wings depending on the light, I will take a photo of the specimen with less magnification.
What we see is the detail of one of the ends of its legs, a "foot", or something like that. I hope you like it.

Absolutely beautiful photo, but I can't make heads or tails of the subject (literally). Which end is this?

I agree about the photo -- wonderfully done!

Scarodactyl, I see this as the last couple of segments of a tarsus, with one large sharp claw visible in front and the other mostly hidden behind that odd blunt claw-shaped lump in the middle. I do not recognize that lump, and I'm wondering if it's a piece of debris stuck on the insect.

I'm eagerly awaiting broader scale views of this insect. If this was shot at only 10X, the beast must be huge.

Very dramatic and sharp. I like the angle very much. What an excellent introduction!

Thanks a lot mates, for your nice words, much appreciated!

Thanks Saul I been becoming crazy with the light, at the end I feel better with the continuous light, sometimes al most shooting in the dark.

Scarodactyl thanks a lot, me neither lol, I was looking for the eye but then I spot very clean the foot, and I decided to give a look, and from a kind of all black fly come all this beautiful colors and details. I will shot a 2x photo today and post, so we can see better. What we see here is the front foot from the front of the fly.

Thanks a lot Rik, I learn a lot from you, so I´m really happy if you like, I will try to stack the other side of the foot, and a smaller shot of the specimen, thanks again!

Thanks a lot Lou, I have also learned a lot from your post. I hope I can contribute more interesting things, thanks for stopping by.

Hello Oscar:

That image seems to me astounding, I like the light and the perspective of it (an unusual point of view). Congratulations.

I agree that the lump on the claw is strange, and looking at the morphology of the claw it appears that it is deformed by that body. Is it not the product of a malformation? ... Something due to an infection or a tumor? I have never observed it in an insect, ... We await the next images from other points of view.

One question: which camera do you use?

The best

Thanks a lot RDolz, I can not help you much, I am far from being an expert in insects, I will try to position the leg upside down and I will make another stack, to see if we can see it well. I used for these stacks Sony a7r3

Thanks Adalbert much appreciate :)

Here we have another stack no very good for the leg, but to show better the bug, here we can see at around 2x more or less. I would love to understand what comes out of the "mouth?"...

pd If anyone knows where I can host it in a very large to share, the original is surprising sharp, that lens is wonderful

Can you show us the whole insect, please? Preferably both side and top views. Single frame snapshots should be fine.

For hosting high resolution, consider a free account at Flickr.

Regarding ID, I'm thinking this is actually some sort of bumblebee, rather than any sort of fly.

See for example the face shots and discussion at https://bybio.wordpress.com/2015/07/27/bumblebee-faces/ .

Hi Oscar, Yes, it has impressive sharpness.

Other free ways to display your images with FULL resolution are www.prodibi.com or www.easyzoom.com

Here are some examples that I uploaded to the forum. They are images captured with the Coolscan 8000, the Coolscan 4000 and the Dimage 5400. All in telecentric mode.

About the lump on the foot...

When I visit https://i.ibb.co/r7S44Cq/fly-med.jpg and zoom in on the left front foot of the subject (right side of the image), I see what looks like the same blob. But in this image, it seems clearly stuck onto the end of both tips of the outside claw, not in any way attached near the middle of the foot as suggested by the first photo.

At this point I'm pretty sure that the lump is debris. It surely makes a nice "what is this?" puzzle piece, though, being so much similar to the middle of the foot in both color and texture.

I agree with Rik, it's a bee with a lump of dirt on it's claw. A quick google search for "bee claw" reveals that bees have a pair of double talons on each foot, i.e. four tips per foot. In this image, the orientation of the forward claw obscures the second point. With the distant claw, the clump of dirt obscures everything but the division between the two points, although I think I can see one of the points through the dirt.
