Sue...it is good to know that about Gall Midge. I see the thrip damage on Roy's daylilies.
Also...that was very good information that you passed on about Milorganite and temperatures. Never heard that before...but it makes sense.
Many times the normal leaf miner is on the oldest leaf. That makes it easy to tear the leaf off all the way down by the crown. I usually find the little yellow miner. I have not been able to find the miner in a mine in the upper part of the leaf. Maybe at that stage it is still too small for my eyes.
The super mines have been on newer leaves that I can not tear off near the bottom of the plant. I am tearing and it never fails to rip in the middle of the mine. The end of the mine is way down in the fan. I have been unable to get that part out. Seeing as daylilies have only one type of miner...I am going to spend extra effort trying to get at the end of one of the super mines and verify that it looks the same.
May your day be spectacular!
