Field Notes
It is a cold November day in Freeport, ME. The temperature is 47 degrees Fahrenheit. We are looking for the winter moth. The winter moth is an invasive species to Maine. We are doing research at the side of a non-busy road. All the trees have lost their leaves but we still found the red maple trees. The ground is slightly frozen. We can see trees, dirt, and rocks in the area we are studying. We are studying in a 3x3 meter area. We are going to look for signs of the winter moth on trees and in the ground. We are happy that in the end we did not find the winter moth.

Supporting Evidence
Photo of my evidence.
We found a cocoon that did not belong to the moth on a tree. We do not know what species it was, only that it was not the winter moth. We know this because the winter moth cocoon is in the ground, not on a tree. The cocoon was 3mm long and 1mm wide.

We dug at the base of some maple trees (3-5 inches down in multiple places) with a spoon and did not find any cocoons or any moths.

We did not see the Winter Moth or any signs of the moth in a 3x3 meter area or anywhere else. We also didn’t find any eggs or larvae that belonged to the moth in the ground and trees. The eggs of the winter moth are tiny little white or orange dots that are in a cluster and are nearly invisible to the naked eye. The larvae look like small green caterpillars with faint stripes on it's back.
