For this project, we focused on leaf miner damage to different species of Elm trees. We collected 25 leaves from two American Elm, two Japanese Elm, and two Smooth Elm trees. We determined the average number of leaf mines and the percent of aborted leaf mines on each species sampled. We found that the American Elm had the highest average number of leaf mines, with the fewest percent aborted. This could mean that the American Elm is more susceptible to leaf miner damage than the other Elm species sampled.
