OK, then there is something else going on in the observation I saw which prompted me to write this.
In the suggestions when you run it, it gives several regionally appropriate choices marked as seen neary such as A. cyanea and A. affinis. However, A. mixta is listed but not indicated as seen nearby (sorry I cant do a screenprint the suggestions dialog closes when I try to switch to my snip tool, but you can run the suggest an ID)
The record is 6 months old - is the "seen nearby" only refreshed infrequently ? That seems an unlikely approach.
So is there some other criteria not being met that results in no "Seen Nearby" for A. mixta here ?
