Hemlock Woolly Adelgid Phenology Training

Phenology is the timing of natural events, when leaves turn colors in the fall, when flowers bloom in the spring, and when animals complete different life stages of growth. Currently, little is known about hemlock woolly adelgid (HWA) phenology across the landscape. A deeper understanding of the life cycle of HWA throughout New York State can tell us where and when to release biocontrol insects, where to monitor for biocontrol establishment, and allow us to track HWA response to different climate factors in the field.

In this training, join one of the New York State Hemlock Initiative’s experienced field technicians as they take you through the yearly phenology of hemlock woolly adelgid. Learn how to identify HWA in the field during any time of year, including just following their summer aestivation period. Learn about why it’s important to track the life cycle of HWA, and how you can help them find out more about HWA and hemlock conservation in your area.
