These are multi-focus microscope photographs I took recently to use as part of a digital reference collection, that is a series of photographs that can be referred to to check whether a future sample is the same ‘morpho species’ as the one in the photograph.
The camera takes up to 50 photos at different focal lengths and then stitches them all together
to create an image that is (almost) completely in focus.
This is advantageous when the subject is so small and the aperture is also small.
For a sense of scale the eye of the lower beetle is around 1mm across, note the mounting pin going through the upper beetle.
I especially like their golden hairs, reminds me of a fluffy dog, not something you think of when handling beetles.
