Unfortunately the only solution with situations like this is to persistently correct all the observations. People use the computer vision suggestions and common names as hints but they will also check other observations to check if they look similar or if the species has been observed nearby. If there are no other observations of the species, or if all the observations have comments saying the species is impossible to identify (which as far as I know is true for Sarcophagids in general), then they might be less likely to identify their own observations as that. Apparently BugGuide is messed up with this family as well which doesn’t help.
If the problem gets too big, you could add it here.
