I moved this post to the Nature Talk area because that seems to be where similar threads are found and I figured it might help others find this thread if it was in the same place. I also created and added a “resources” tag since that seems to be a keyword in these types of threads. Here are some examples of other threads on specific taxa that might be of interest:

Some of them include links to iNat journal posts, but many are resources that are off iNat as well. There are probably others that could be added to that list/this thread.
