Fly Bubbling

I found some more flies indulging in this mysterious pastime (it appears that there is still no clear understanding of why they do it)

I like these as the bubbles are much more clean and transparent than those I've seen before

I really like using the mk2 + 60mm macro for macro work

See what you think

Re: Fly Bubbling

Hi Brian, i am just a newbie to photography, but i find these macro shots absolutely fantastic, i have just purchased an EM 5 and a couple of lenses, my priority now is to save up for a 60mm macro lens, thanks for the inspiration (my wife is tut-tutting at the side of me)

Re: Fly Bubbling

thanks Mick, they don't dribble but regurgitate a bubble on the end of their tongue and then suck it back in and repeat.

One of many theories on why they do it is that they are increasing the rate of digestion by oxidising it because of the larger surface area of the bubble

here's a link to a small cropped image from some time back showing the tongue in "Ready to bubble" shape

Re: Fly Bubbling

here are a couple more shots from today of another fly species also bubbling, not so good as images but it shows the fly extruding its tongue and then blowing the bubble

(If you use your imagination in the second shot you can see the "bubble tongue" shape through the bubble )

Re: Fly Bubbling

Very good but a question please.

Are these pictures taken using the 60mm Macro only, or do you need extension tubes with it ?

I have tried, not very successfully, to get 'macro' shots using my E620 with the 70-300mm lens, but no tubes or bellows.

I am interested in 'How do you do it ?'

Thanks

Re: Fly Bubbling

I wondered if they do it to aid cooling? I remember seeing lots of flies doing it in the evening, when I was on a caravan site near Hexham many years ago. Most of them were even more spectacular than your images, with their tongue stuck further out, and the bubble very much on the end of it, well away from the 'face'. Disgusting habit, really!

But flies vomit on their food anyway, don't they, then stir it with a foot as it starts to dissolve the food, and then suck it back up. Maybe they are just hungry....

these are shot using the "bare" 60mm macro, no tubes or mag filters, then cropped for composition and detail (to give you an idea of the size of crop its possible to get away with if you have good focus and exposure, this is the original from which the Fly Bubbling Side view was cropped)

It is possible to fill the frame more but I sometimes prefer to shoot from further away and be sure of getting the image I want, knowing that I can crop afterwards

I've read various "learned papers" on the subject and there are a variety of theories (quite possible all correct ) to explain what is going on, this is a short article on it I just spotted

http://www.urbanwildlifeguide.net/20...owing-fly.html

They may appear disgusting but the world would be a pretty bad place if they weren't doing their job - so let's hear it for flies, I reckon they are no worse than gum chewing brats

That was tongue in cheek, Brian! Thanks for the link - interesting. They are probably not as bad as gum-chewing brats - well those that drop it, stick it under tables, chairs, etc., etc! Antisocial morons.....

Re: Fly Bubbling

Thanks Brian

Considering the size of the crop that is an amazing amount of detail without pixelation.

Re: Fly Bubbling

David, its down to the quality of the sensor, lens and Olympus TruPic 7

Then all you need is correct focus and exposure and it does the rest for you
