It's always interesting for me to see the internal muscles and structures that show up when crossed polarizers are used. I loaded an eyedropper with some water from a nearly dried up birdbath and it was full of mosquito and midge larvae.


The shot below is an overall of one of the specimens on the slide. The white sections that look a little like stretched rubber bands are muscles that are hard to see in "normal" light.

The image below is of the head of a specimen. The muscle fiber is quite interesting in this view.

This last image takes a little explaining. We are looking "into" the body of this larva at a fairly high magnification. The golden colored "tubing" is for air, and it runs directly to the breathing tube. (There are two air tubes that start at the end of the snorkel and run the length of the body with branches at various locations). The white colored muscle fiber can also be seen nicely here. It is connected to the interior surface of the (relatively) clear body tube of the abdomen.

Fantastic images Charlie, you really got into some detail in that last one especially but of course all of them show great details. Very Happy
