Hedgehog

I found this fascinating looking pupa whilst stacking firewood - it looked exactly like a mini-hedgehog without features.

When I did a Google Lens query on it, the answer came back as  ... 'hedgehog,' which I KNOW it is not. I guess the search query and I were on the same page.

It looks like a pupa of one of those hairy caterpillars (tussock moth caterpillars) that includes its hairy tufts in its pupa-making, making for a fuzzy cocoon.
