So here I am, well past bedtime, with a new batch of photos of springtail bellies to examine. But not now; tomorrow.
For now, here's one that stopped to investigate something for a second or two.
|I think this one is Entomobrya nivalis, one of the "slender" springtails. Between leaps, it is usually running. About 1.5 mm long.|
And now, goodnight!
