Problems with Computer Vision and new/inexperienced users

The problem is that your observation could also easily get stuck somewhere where it does not belong. As the iNaturalist suggestions also say: The “best approach” is to just ID as far as you confidently can on your own. If you just put “arthropod” in there, then there are enough people working on that group that will push it further into the right direction so that it will get to the level of where the “experts” are (if there are any for the specific group).
