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.

Microscopy as art

Posted by wildwatertv on August 20, 2010

A friend of mine, Julian Barton, suggested that microscopy could be used to produce artistic as well as scientific images.  Sort of landscapes within the miniature world.  There is a good history of this, with Spike Walker being represented by the Wellcome Institute at an exhibition recently of his electron micrographs.  This is my first attempt.  Greenbottles (Lucilla Caesar) have an amazing irridescent quality when you see them, and it is just about possible to reproduce this photographically.  These two pics are of the abdomen and thorax of a greenbottle.  I think I like the first one best, due to its cartoon like quality, but comments are appreciated.  Julian, I hope this is what you meant.  Taken through a light microscope using a Nikon 10xDIC objective with reflected flash light.

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!

Nigella seed

Posted by wildwatertv on January 22, 2010

This shows two different magnifications of a single seed, genus Nigella, known as love-in-a-mist.  The seeds are sometimes used in Indian cookery as a spice, and are individually about 1mm long.  they have the most extraordinary texture and a surface almost like crocodile skin. I’m working on a catalogue of microscopic images of seeds and this is so far the most beautiful one I’ve seen.  Zeiss Luminar, light microscope, Nikon 10x/2.5x Objective/photo-eyepiece.

Vinyl record

Posted by wildwatertv on December 16, 2009

This is a photograph showing how the sound is made on a vinyl record.  The needle is made to vibrate as it runs along the grooves.  The more wobbly the line, the higher the pitch of the sound.  It was a great system, and vinyl is still favoured by many for the distinct tone it gives. This portion of the record is about 1mm long, so a split second of sound is all that is shown here.  Thanks to Thor Haugen for the idea (and the record).  It’s a pointer sisters track, by the way, I wonder which bit?

Compound eyes 2

Posted by wildwatertv on November 9, 2009

waspeyeblog

This is the eye of a wasp.  Unlike bees they have clean compound eyes, very highly developed.  The structure is a honeycomb of hexagonal elements, which combine to form a rudimentary image.  They eyes cannot focus like human eyes, but they can see in most directions at the same time, which gives the insect a clear warning when anything approaches. Taken through a Swift Microscope with a 4x objective.

The pen is mightier than the sword

Slightly more prosaic subject matter, but ballpoint pens are really a miracle of engineering.  When you use them they pick up small pieces of paper and fibres.  These eventually go inside the ball and clog up the mechanism, but considering the balls are far less than a millimetre in diameter it’s amazing they work so often.  I’ve spent all morning seeing the differences between brands and they vary enormously.  Lighting them is also a challenge.

Sweets? No, more pollen.

Posted by wildwatertv on October 21, 2009

 

pollenlilyblogThis looks like sugar coated sweets, but it’s actually lily pollen.  This is the stuff that stains all the curtains and gets everywhere.  It’s sticky, but colourful.  Each grain of pollen has a sticky surface which allows it to be collected by pollenating insects such as bees.  Because of its colour, it also makes a great subject for microphotography.  This was taken using a Nikon Achromat x10 microscope objective and highly modified Lomo microscope with a fabricated Nikon Phototube.

Lepidoptera

Lepidoptera are butterflies and moths.  Although we generally just see their wings they have interesting faces too.  The top image is a night flying moth caller the silver y moth, or Autographa gamma.  It is so called because on the dark brown wings there appears to be a small letter as in the picture below the face.  The bottom image is the face of a painted lady butterfly (Vanessa cardui). The fascinating thing about these animals is the way they gather food.  They taste with their feet and use the long rolled up tongue to reach the deepest nectaries of flowers.  The tongue is just a drinking tube really.
