30 March 2008, New Brunswick, Canada. Muscidae: Caricea sp. a key to the NA genera separates Caricea from Coenosia and 6 other genera : pair of orbital setae on each side of frons; pair of frontal setae on each side of frons- Caricea : usually 1 orbital and 3 frontal setae on each side of frons - Coenosia etc. Tony T attached the following image:  [165.26Kb] |

In Europe these two genera are (I believe) considered synonymous |

I think Caricea is Lispocephala in old World. Magnificent, Dazzling, absolutely Marvelous shot.   Stephane. |

The image is a composite of many images stacked with Helicon Focus. Such an image can only be obtained by stacking images but the overlapping setae and large depth of field cause problems for the software. However, Helicon Focus is an incredible program for obtaining this type of image. |

I agree with St?phane - I think this may be your best ever image on Diptera.info. We are so lucky to have you.

It's an amazing image. I wonder if anyone ever have made a photo of a whole fly in that large magnification scale (stacking + stitching). That would be a fantastic gigantic fly photo

The full-frame image is here. The original is 4,288 pixels wide; this means that it would make a print 18" wide (@240ppi resolution). So, a similar photo of the posterior end should allow one to get a good print, after stitching) that is 1 meter wide. Trouble is it would be difficult to display on a computer monitor

I had a look at that site; very impressive. Not sure how it would work with Diptera.info. Diptera. info restricts image size to 200KB, the original image is 34,900KB. Zooming in on a 200KB will probably give lousy resolution; that is even if it would be possible to zoom in on a Diptera.info image. Interesting idea but way beyond my capabilities of computer "skills". |

About Zoomify. I have tried it a long time ago on an image of a large hand drawn map. It is nice to be able to see an overview and be able to zoom in to see each line in detail, but it is only suitable for a few images because Zoomify creates alot of images from the original. Not very practical from an administrators point of view. |

That would be a fantastic gigantic fly photo Photographed another specimen and made a print on the largest paper I have at the moment (279 x 432mm). Came out OK, body length of the actual fly is 5mm, on the print it is 180mm. Was restricted in the amount of magnification by the width of the paper. Must try making a print of a 'long' fly.

Fantastic. What incredible results. A coffee table book of photos like this would be every entomologist's dream!
