7 April 2008, New Brunswick, Canada.
Very close to, and with similar habits, Culex pipiens
Be careful what you wish forPfft. Been waiting for some new flies to appear (plenty of Pollenia spp. flying) but didn't want the mosquito season to start so earlySad.

Note the blurry antennae, must have been the slightest of air movement (undetectable by me) that was picked up by the antennae.

Nothing is more humbling than to look with a strong magnifying glass at an insect so tiny that the naked eye sees only the barest speck and to discover that nevertheless it is sculpted and articulated and striped with the same care and imagination as a zebra. Apparently it does not occur to nature whether or not a creature is within our range of vision, and the suspicion arises that even the zebra was not designed for our benefit.

Mind you - that is one weird looking beastie. Another triumph Tony Grin

Thanks Susan.
Perhaps even more amazing are the structures found in some microscopic life; animals we cannot even see with the naked eye. Take a look at some of the posts on photomacrography

Photos made with a digital camera (a DSLR). To get high magnification all one has to do is to attach extension tubes or a bellows to the camera and then attach a wide angle lens, in reverse, to the bellows. In this case a 28mm lens mounted in reverse (backwards).

As usual Tony, these photos are just superb. What kind of magnification do you think you are achieving in the full size file ? The refraction in the eyes is wonderful.

Hi Nigel:
Didn't record the mag. in this instance, and I don't have the mosquito.
I have a Nikon PB-6 bellows. The literature that came with the AF 28mm f2.8D Nikkor lens gives a mag. range of 3.2-7.6 when reversed on the PB-6, and a field size getting down to 3.2x4.7mm.I believe these data are based on the full-sized sensor in regular SLR's; possibly need to increase the mag. range by 1.5 to acount for the smaller sensors in most DSLR's.
A wider angle lens, e.g., 24mm will give even greater mag.; a longer lens, e.g., 50mm will give less mag.
Also, using the 28mm in the normal position on the PB-6 will give mag. from 1.7-4 (again I guess with a full-sized sensor).
At these mags. depth of field is almost non-existant; had to use many images and stack them with Helicon Focus.

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
