The highly anticipated emergence of the Great Eastern Brood, Brood X of the 17-year periodical cicadas in 2021, with a large footprint in northeastern US, was the focus of widespread research and education by entomologists. What did we learn? Who and how many did we reach? What questions remain? This webinar, sponsored by the Eastern Branch, will review early findings, outreach activities, and new questions from our fellow entomologists, and provide an opportunity for discussion of a range of topics on the cicada emergence.
