“A water-stick insect does not want to be seen” (Pymatuning Wetlands 2015, Day 8)
Today was the midterm exam. The students looked a bit tired this morning. The first half of the exam was in the classroom and the second half was in the field. Word on the wetland street is that the first part was challenging, but the plant identifications were straightforward. As it should be.
We went to Geneva marsh this afternoon and began sampling macroinvertebrates as part of a comparative ecology project. We will sample marsh and shallow pond sites under open and closed canopies, and sites with and without fish. Two wetlands were sampled this afternoon, including Geneva marsh itself and a nearby pond. The students then spent the rest of the afternoon isolating the macroinvertebrates from their samples. One student in the class has been proclaiming that he really wants to see a walking-stick insect (because as he says, they don’t really want to be seen). I think he was pleasantly surprised that we did collect the “wetland-version” of this morphology today, a water-stick insect (family Nepitae).
Tomorrow we will sample another two sites and begin to identify and tally our collections.
