Did not measure.

In all, I did a very poor job with this batch of springtails (1, 2, 3, 4, 5, 6) I found near a marsh on a small log partially covered (esp. on bottom) with a layer of dry, brown fungus. For some reason they all died soon after placement in my light arena despite frequent mistings to prevent dehydration. Then, while photographing their tiny corpses I seem to have forgotten to shoot any next to a millimeter rule. Finally, I cannot atest that any of these photos are of the same individual, so I will probably unlink them after posting them with the same set of data.
