This is Dicyrtomina saundersi, a springtail, and boy do they jump if they feel threatened. This is an uncropped image. I have experimented with extension tubes for the first time ever this morning, and have found using the 36 mm tube in combination with my Raynox 250 they work pretty well. Normally I would have had to crop the image some to get closer.
The original image was 6000 x 4000 pixels but I have reduced it down to 2000 x 1333 pixels for internet use and have reduced the quality a little to bring down the file size.
Oh, and yes, I probably snapped this individual at an inopportune moment … but there you go in the world of photography.
