Eumenes wasp mud nest pots.
There were a dozen of these mantid egg cases in this patch of Rhus aromatica, the same spot I found the mud nests in.
If there were sheep about, I say this was a bit of wool with a medium-sized marble in it. I am, however, hoping it’s some insect I know nothing about making it through the winter. It was too high up in a tree to touch. Those are pine needles stuck to it.
Bird skull.
