Banded tussock moth (Halysidota tessellaris) caterpillar with stemmata peeking out from behind the anterior tufts. The second photograph shows the barbed setae, which will eventually be detached and rewoven into the cocoon.

This is a newly-molted variable oakleaf caterpillar (Lochmaeus manteo), with old head capsule still attached. I initially thought the capsule was the head and that the thorax had eyespots, but John and Jane Balaban on Bugguide.net pointed out the obvious to me.
This species sprays formic acid, apparently.
FYI, Al Denelsbeck posted an almost identical image here, complete with close-up of the eyes.
While searching for yellow brain fungus on a hot day in December, I stumbled across this twisted little blob of gunk nestled in a bark crevice. At first I was all excited that it might be some sort of snow fungus (e.g., Tremella fuciformis) that was past its prime, but I’m pretty sure it’s just resin, gum, or sap — not sure which. But I’ve never seen resin with little spheres blebbing out, and nothing with a white membrane. It’s creepy. If you have more information or have wild speculation, please send me a note or leave a comment. Approximately 1″ long. Photographed at Lake Mohonk, New Paltz, New York.
I really had wanted this to be a slime mold … perhaps an immature Trichia or Stemonitis. If you’re a slime mold fan, please weigh in.
Sycamore tussock moth (Halysidota harrisii) caterpillar at Hildacy Farm Preserve in Media, PA. I remember these as a child mainly because of their urticating hairs. But they are also really, really cute. I especially like the white ones because their orange tufts stand out better than on the yellow variety. Don’t you just want to pick it up?? If by chance you don’t know what “urticating” means, I highly recommend the experience. You won’t forget.
Here’s a fun trick for Thanksgiving. If you get into an argument about whether you purchased yams or sweet potatoes at the store, chop one in half before cooking and look for milky white sap bleeding off the flesh. Only sweet potatoes do that. But if you don’t see sap, that might mean you just have an old sweet potato, so don’t place large bets when doing this.
