Today we collected some leaf specimens from the elm trees on campus. It took quite a bit of time to get our specimens and not all of the trees even had leafminer activity. But we wanted to be thorough and it took some time to check. Many of the trees had leafminer activity. Most of them looked like stigmella multispicata but we can’t immediately be sure. It will require a little more investigation to be certain. One tree looked like it was covered in warts. That one did have one leafmine. It started to storm which made things a little more difficult but my partner had waterproof paper. We photographed all the trees that had leafminer and also took individual photos of the branches and surrounding ten leaves. We did see a couple of things that looked like blotch mines too.
