Popcorn mimics

I have been busy sorting out the anatomy of a collection of various species of springtails; difficult primarily because of their springiness. I never see them leap; they're just not where they were an instant ago. Half my photos are of empty spaces.

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!
