… I agree to what @susanhewitt says on moths. My experience was that it dramatically improved from last year to this year. There are a number of species which I had to type in last year, and in 2020 they are suggested by the system. That’s good!
I also noticed that, surprisingly, the system fails for moths with clear and simple designs, e.g., neotropical Arctiinae which are black with very simple white stripes. On the other hand, very complex coloring patterns are surprisingly well identified, like some European Boarmiini species which are just grey in grey!
Finally, a funny one, show it a blurry photo of a Buddleja flower and it may come up suggesting some of the common butterflies / hawk moths usually found on it! ;-)
