The last hour of todays class was spent inspecting vairous species of elm trees for the presence of mines. We are peticularly interested in finding Stigmella multispicata mines. The elm's with the most mines are the ones behind Morrell II. No leafminer activity was observed by myself, Stefanie, or Ivan in any of the trees west of Morrell. We did however, see a lot of the resistant american elm with galls on the leaves. Seeing all of these galls I wonder if they are feeding on the leafminers??
After class I drove up N Residential Drive to look at the 7 Siberian Elms. I Did not spend a bunch of time there but I did look closley at the leaves and once again there was no activity to be seen. THis is odd. I am begining to wonder if there is something in the area of the Morrell building that is attracting these moths. That is something that is out of the scope of this class. This is were we learn to write about these things, not actually research them. From what I have read about these studies they have ocured over a much longer period of time then this class would have time for.
