@janetwright @jilliankern @kiwifergus and all – yes, it currently seems to be a priority to develop some way to collect this kind of information on the Taxon Pages. Relevant discussions here:

https://forum.inaturalist.org/t/adding-useful-id-info-to-taxon-pages/657
So hopefully someday in the near future there will be more organized locations to paste all of the great information being posted here!
