Hover fly or syrphid fly portrait

Posted by wildwatertv on September 3, 2010

Extreme close up of the head of the syrphid or hover fly, Eupeodes luniger, showing the structure of the compound eyes.  My interest in these creatures seems to be growing, and I’m still struggling to get the absolute maximum detail available with transmitted light. The more I see of insects, the more I admire them. Stacked using 110 images taken with a Nikon 10x DIC objective using flash. Nikon D300. Modified Lomo microscope with a short tube.

House Fly’s mouth

Posted by wildwatertv on June 8, 2010

This creature is the common house fly, musca domestica. When you see them sitting on a piece of bread they are using that fearsome mouth to scrape and suck food from the bread, cheese, or anything else they might like…  It excretes a sort of liquid enzyme which digests the food on the surface before sucking the pre-digested liquid up though the tube.  These mouth-parts are always a bit grubby.  Pays to keep them off your food in the first place.  Now I’ve seen one up close I think I’ll be more careful.

Taken through a light microscope with a Nikon x10DIC .25 objective and stacked using a stack of thirty-four images.

More eyes

Posted by wildwatertv on June 3, 2010


Sometimes you take a picture which makes you want to throw everything else you’ve ever done away and just simply admire the majesty of nature.  I’ve posted a blow-up of the central portion of this picture to show the perfection that exists on such a small scale.  Taken through a light microscope using a Nikon DI 10x objective and using a stack of fifty images, this is a different sort of hoverfly to the one below.  This one is called Eupeodes corollae.  One of the most common flies in the garden this time of year.  Wonderful creature!

Hover Fly eyes

Posted by wildwatertv on May 28, 2010

This beast is the common hoverfly, Melascaeava cinctella.  It has excellent vision, and extremely well developed compound eyes.  This photograph also shows the three small simple eyes, or ocelli, arranged in a triangle between the two enormous compound eyes.  Photographic image stack using a Zeiss Luminar 25mm on a standard light microscope.

Compound eyes part one

This fly on a leaf was shot using a Zeiss Luminar.  The size of the animal was about 5mm.  The detail below shows the structure of an insect’s eye.  The honeycomb pattern varies from species to species, but this is a fine example of one of the more highly developed eyes in the insect kingdom.  Each segment of the eye can be thought of as a pixel, and the image the fly sees is dependent only on the number of facets it has available.  Simpler insects have far fewer.
