Freshwater aquatic zooplankton and algae under microscope view
Squash preparation of  onion root tip cells stained to reveal chromosomes,  Bright field illumination, light microscopy.  This image was taken with the X40 objective lens.  Depth of focus is extremely low at this magnification.  Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced.  The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
Demodex folliculorum - parasitic mite on the eyelashes of a human eye, microscope
Hemlock woolly adelgid (HWA) infestation on underside of eastern hemlock branch in Connecticut. This tiny sapsucking insect from Asia, discovered in Virginia in 1951, is a major killer of eastern hemlocks, which are vitally important to Northeastern forest ecosystems. HWA is named for its woolly egg masses. Thanks to introduction of the Japanese ladybeetle, a predator of HWA, many hemlocks in Connecticut have survived since the first waves of tree mortality some 35 years ago.
