Before the swap, Macrorrhinia endonephele didn’t have any establishment means listed on its taxon page. All of these establishment means from Arcola malloi should have transferred to Macrorrhinia endonephele when the taxon change was committed.
I don’t know if this is the first time in a swap that both were valid taxa, both had obs, but one was Introduced and the other presumed Native.
In this case, A malloi was always Introduced, and M. endonephele was always thought to be Native. Is it expected when two taxa merge that the “receiving” taxon takes on the establishment means of the “donor” taxa for the entire taxon?
I believe from a programming perspective Unknown is an establishment means. There are no blanks in that field; each has one of 4 establishment means. So I don’t think it matters whether the receiving taxon is presumed or specifically listed to be native. The fact is simply that one was Introduced and the other was Unknown.
The two questions are:
Specific: Why did some, but not all, of the Arcola malloi obs keep Introduced status when swapped into Macrorrhinia endonephele?
General: Is it expected, or should it be expected, that when two taxa merge, each with different establishment means (and I include Unknown as an establishment means with Introduced, Native, Endemic) for the entire country, that the “receiving” taxon takes on the establishment means of the “donor” taxon for the entire taxon, in all places, and including already existing obs?
SMH! I learned something I should have already known. Never noticed the filter in Identify for Reviewed (any, yes, no) where the default is No. Since I’d reviewed all of them, naturally my result was 0. That also explains why I’ve sometimes missed obs when updating manually; I hadn’t changed the filter to “any”.
