Field Notes
On November 9th, We were searching for the Hemlock Wooly Adelgid behind the Freeport Middle School pond in Freeport ME about 30-35 meters from the highway on a brisk 47°F day. If you look around you can see a variety of trees. For example, pine, birch, and hemlock trees cover ¾ of the area. We can hear the cars fly by on the highway and you can hear leaves rustle around from the cool breeze. We were surprised we didn't find the Hemlock Wooly Adelgid because in the small 5 square meter area we found close to five hemlock trees about a ½ meter apart from each other.

Supporting Evidence
Photo of my evidence.
The hemlock tree has a ½ cm thick branch. On the bottom side of the thin, sharp needles there are two thin white stripes to help indicate the Hemlock tree.

We know that we did NOT find the Hemlock Wooly Adelgid because when looking at the base of the needles we could not find small white waxy tuffs that would indicate there would be a hemlock wooly infestation.

We also did not find the milky white color eggs that the HWA has.
