Tiny yellow insect, Heesch, Netherlands

This has to be one of the smallest insects I've ever photographed. Inspecting the white sheet of my moth light trap, I noticed a little orange speckle. I figured to try and capture it, which was very hard. I focused at the closest focusing distance my macro lens allows, which makes this a 1:1 magnification.

With the subject still this tiny in the scene at maximum magnification, we can do the math to determine its size. From head to abdomen, is 456 pixels of height. Out of the 5504 of pixels of height of the full scene. Knowing the fragment it takes up in height, we can apply that to the sensor height, which is 23.9mm. That makes this insects body 1.98mm in size.

And here's the deep crop:

Note how at this magnification, that silky white blanket isn't that white at all.
