Cold weather babies

Looking under fallen, rained-on, rotting maple leaves for tiny flies to feed tinier spiders, I found a couple of snails instead:

This was the big one. 4 millimeters, eyes to back bumper.

And this pupa or egg case, under 2 mm. across, was sandwiched between two leaves. (This was four days ago; I looked at it again tonight, and the casing seems to have thinned, and I can see segments inside. I think it's a pupa. I hope it hatches.)

Almost flying-saucer shaped, then. Now it's longer, and brown at the tip. 

And the spiders got three miniature golden flies or wasps.

I'm still working on evil mussels. Story tomorrow, I think.
