Referring to this taxon: Blue-bordered Pedunculate Ground Beetle Pasimachus elongatus This species has a number of records from the Eastern/Southeastern US here on iNaturalist. I believe that is a systematic error based on over-specific ID’s originating in computer vision suggestions. Species ID i…

Unfortunately a common problem with iNaturalist’s CV. Similar problems with taxa like Phyllophaga anxia and Heterocerus fenestratus being selected because the CV has trained on a small number of species in a genus (or only one species). But that’s another can of worms I suppose. I’ll try to help …

Thanks. I should add that this sort of problem is not unique to computer-assisted ID. People are quite capable of repeating the same sort of mistake. This is one reason I am a big fan of marking observations “as good as it can get” at higher taxon levels when appropriate. It keeps things realistic,…

I did NC and SC. There are a few obs. where several people agreed to the wrong ID, so those are still showing up. At least there are now no research grade observations from either state. Edit. Also did Georgia. Edit. New Jersey. Edit. Not clear what to do about KY, TN, AL, MS. Reported range ext…

[image] cotinis: Not clear what to do about KY, TN, AL, MS. Reported range extends east to Indiana, and parts of Louisiana, I think I would say on a case by case basis. I don’t think it will occur in MS or AL. Western TN and KY might be possible, but certainly not anything in the Appalachian …

Good ideas. I see some observations from the Blue Ridge of TN/KY that should be addressed. East of Mississippi River and south of Ohio River seem like reasonable boundaries for clearly out-of-range. More generically, perhaps in the future there will be a way for the cv system to “know” which specie…

Based on another discussion, I think one approach to this issue would be to remove individual Pasimachus species from the computer vision (cv) model. That way the system will not suggest those species. I am unclear on both the mechanics of how this might work and how one could request that change to…

[image] cotinis: I think one approach to this issue would be to remove individual Pasimachus species from the computer vision (cv) model. That sounds like a snowball waiting to happen. If we do this with Sinea, then with Pasimachus, then every identifier of difficult taxa will want it for the…

that seems like a good thing to me better to have correct higher-level IDs than incorrect species IDs

Let us please not restart another back-and-forth discussion between the “everything deserves a species ID“ and “not everything is identifiable to species” camps, it’s already been discussed to death in countless threads. [image] cotinis: I think one approach to this issue would be to remove ind…

[image] bradbarnd: There are so many… [image] Phyllophaga anxia will almost certainly get out of control if not removed from the CV. Because of the lack of other Phyllophaga species in the CV, it will be the top suggestion for many different Phyllophaga. Really any Phyllophaga learned need …
