What is the RAREST animal/plant you have ever seen

Azorella pulvinata


I have a new rarest find since my last reply in April. It is an iNat first, found during the City Nature Challenge 2023:


It’s a pygmy grasshopper, Paxilla obesa, that was most commonly collected from 1900 to the 1930s and I believe has been collected only twice since then, although most recorded specimens here have no date. I think I hold the only photos of the species in situ and hold the southernmost observation site. I did not collect it as this would be illegal in the Everglades National Park and I didn’t know what it was at the time. I hope to go back there and get better photos in the future.
