Only been on INat for about a month but I did get a handful of ā€˜under 1000 total observation’ species. Rarest that I’m 100% confidant was ID’d correctly is this beauty, the Black Margate, 653 observations total.

If you just want a list of the rarest taxa you’ve seen this tool gives it as a ranked list for what it’s worth

That tool is really nice in terms of being able to pull togather your rare find/only observer pics. Of course any of these is a testiment to the IDers skilled enough to ID a species without other photos. I am sure I have many more that could be here, but I lack the skills to confirm those species. I dont know if these rare finds are that rare, as much as, noone knows (or desires) how to look.

Cheers, those flies are really cool, I was pretty psyched when I found one in the jungles of Sumatra.

I haven’t seen any ā€œrareā€ animals/plants I don’t think, but in terms of number of global observations, my rarest observation is a quillback I saw this summer, which only has 457 observations other than mine. Not impressive but someday I will find something more rare, maybe even discover a new species.

Schistura Hiranyakeshi, a fish endemic to only one pond in the whole world! Named after the Hiranyakeshi temple in front of which it is found in Amboli, MH (india) Oddly enough, I think mine is the one of 13 observations on iNat which is slightly mind-blowing

A new rarity for me. Wallaciana namadgi a treehopper in the tribe Terentiini hat was discovered in the Namadgi National Park after which it is named. As far as I’m aware this is the only live photos of the species. https://inaturalist.ala.org.au/observations/333403926

Common ringed plover, I have no idea how to tell how many times it has been seen in Maine

But I am guessing around 3. I drove 100 miles at -20 -30F. Got there at dawn got some pics 2 minutes later it died.

Found while not even looking for wildlife, of course… haha! 68 observations currently, mine was 52nd and 1st in Connecticut.

Wish I could learn more about my rare find, but sadly there isn’t a lot of information about it (of course :frowning: )

I will also add a recent confirmation for https://www.inaturalist.org/observations/331462846 , which while not rare on a global or even state scale, is often only considered native ~25 miles north and 1000 feet up. I was also proud of this find since the invasive P. abies is a constant source of confusion as a lookalike.

On this note, it is the first research-grade observation of this species in the county!

The rarest thing I’ve seen, in iNat, is a beetle I photographed on a bluebonnet during a mostly bluebonnet-free drive through my favorite bluebonnet peeping location in 2023. My photo of it became the default photo of the species probably because, of the 4 observations in iNat, mine was the only photo of the insect alive and in the wild.

Discovering that it was rare gave me quite a thrill, but my fellow flower peepers were not amused.
