Hemlock Woolly Adelgid Citizen Scientist Training November 1st
Although autumn is just beginning here in Western New York, the winter season will soon be upon us. The colder months, November through March to be exact, is the perfect time of year to search the area’s forests for an invasive forest pest known as Hemlock Woolly Adelgid (HWA). HWA is an aphid-like insect, originating from Asia, which feeds off of the food storage cells below the needles of an Eastern Hemlock tree and hides itself under white woolly masses for protection. Within only a matter of 4-10 years an individual tree can succumb to an HWA infestation if left unnoticed. This deadly...

During a recent Hemlock Woolly Adelgid survey, one of our volunteers found a little yellow blob attached to a hemlock twig. The mass was clearly not HWA, but curiosity prompted me to bring it back to the office for examination. A closer look under the microscope revealed that the blob actually consisted of a powdery fungus encapsulating a dead spider! After a bit of research, I came to suspect that it might be some sort of Cordyceps; a genus of parasitic fungi capable of taking control of an arthropod, thus directing it to navigate to a favorable position for the fungi’s spores to...

Don’t forget to join us tomorrow for our first Hemlock Woolly Adelgid survey of the season! We will be meeting at Dobbin’s Woods, a Chautauqua Watershed Conservancy property, at 9:30AM. With our recent snows and predicted cold temperatures, please be sure to dress warmly and bring some snowshoes or skis to get around as the snow pack will be deep. We will have some extra snowshoes available if needed. For directions to the site, please visit: http://chautauquawatershed.org/index.php/preserves/our-preserves

While old man winter seemed to have taken a break this past season, we certainly did not as there was much work to be done! As you likely saw, we spent much of this past winter season getting into the field to survey for Hemlock Woolly Adelgid (Adelges tsugae), an invasive insect threatening our local hemlock trees (Tsuga canandensis) and forests. Throughout the course of our field work and educational outreach programs, we not only had the opportunity to spread the word about this pest in attempts to slow the spread of it into our area, but also had the opportunity to learn a lot more about...
Read MoreHWA Survey Season
Once again it’s that time of year to brave the cold for conservation sake! That’s right, the season for surveying Eastern Hemlock trees (Tsuga canadensis) for the presence of Hemlock Woolly Adelgid (Adelges tsugae) has officially begun. Commonly referred to as HWA, Hemlock Woolly Adelgid is an aphid-like invasive insect that specifically attacks species within the Tsuga genus. Within the United States, four species of hemlock exist: Western and Mountain hemlock in the Pacific Northwest and Eastern and Carolina hemlock throughout the east. Each of these species are fair game for...
