As you can see at https://www.inaturalist.org/observations/33726122, I’ve IDed this observation to species 3 separate times and each time my ID has reverted to a genus ID. I’m 100% sure of the species ID (regardless of the taxon split), but I can’t get it to stick. It’s also worrying that the total number of IDs for Carolina mantis (which is a very common insect in the U.S.) is currently 84. Is this some kind of botched taxon split that keeps getting reapplied? Not sure what’s going on exactly.
Regarding the taxon split itself, the new species that was split off from Stagmomantis carolina only occurs in the southern U.S., midwest, and Mexico, so it should never have affected Stagmomantis carolina observations in Pennsylvania.
