I believe this is Apheloria virginiensis. I did indeed get so lost in looking at it that I couldn’t remember where I was until I stood up. And it’s not as if I’d never seen one of these before; they’re fairly common in the forest leaf duff.
I processed this on my phone, as usual, and didn’t notice until uploading it to the laptop just now that it’s slightly fuzzy. Oh well.
Good to find a use once again for the target-shaped text option in Snapseed. The auto-generated font sizes and lines were a good fit for this tanka as well, I think. All in all, I’d say my smugness about this haiga-like thing is appropriate for the day, which has long been mainly an exercise in corporate greenwashing and liberal performative virtue.
