Join us to learn more about the HWA, how to identify it and what we can do about the infestation.
Finger Lakes PRISM is the Partnership for Regional Invasive Species Management at Hobart and William Smith Colleges. Their focus is educating the public on invasive species to build community awareness and participation.
The hemlock woolly adelgid, or HWA, is an invasive, aphid-like insect that is threatening the eastern hemlock, one of our important tree species in this area. HWA are very small (1.5 mm) and often hard to see, but they can be easily identified by the white woolly masses they form on the underside of branches at the base of the needles.
