The AHS Daylily Dictionary has pictures of all the above except mite damage, see:

It's difficult to do a comprehensive presentation of what you're looking for because it's not always possible to identify a problem based on a picture, it may need a lab analysis and even then be inconclusive. Some problems can look very much alike. I have some pictures of mite damage (I posted one earlier in another thread, forget which one) and thrips damage and maybe a few other things that I can post on your thread when I get a moment. Sometimes with visual problems one also needs a history and to see the whole plant, though, to be able to take a shot at what the problem is.
