Schools Tracking the Woolly Bully-2015

Schools Tracking  the Woolly Bully at field site and field trip

Students from Amherst Regional High School and the MacDuffie School look near and far to find traces of the Hemlock Woolly Adelgid and its impact on our forests.

Amherst Regional High School South Campus students took an up-close look at some mysterious tiny creatures they discovered while searching for the Woolly Adelgid at their schoolyard field site.

Here are some pictures a student took when we were looking at a woolly hemlock branch under the microscope.  These look like spiders.  We noticed a lot of web-like material in addition to the egg sacs.

Response from Project Ecologist, Dr. David Orwig:

Great pictures of spider mites, which are very common on hemlock branches, and why you observed web-like material.
