Ephemeroptera Plecoptera Preface


Because of uncertainty about hosting an international, in-person conference in mid-2021, our meeting was postponed until summer 2022. Uncertainty continued into 2022. We could not wait longer, so The Joint Meeting of the XVI International Conference on Ephemeroptera and XX International Symposium on Plecoptera was a virtual affair hosted from the University of Illinois Urbana Champaign, U.S.A. The conference occurred daily, 0600–0900 hrs Chicago time, 26–29 July 2022. Despite the virtual venue, 41 oral (video) and 26 poster presentations were given by a total of 133 authors, representing 28 countries. At least 196 unique persons attended the 12 hrs of conference. It was a surprisingly successful meeting. The meeting program and links to all presentations are available from Plecoptera Species File. There were no Lifetime Achievement Awards bestowed upon our members during this meeting. A proposal for a meeting in 2024 in Turin, Italy was presented and accepted. In the weeks following the conference, we learned of the tragic death of our good friend and colleague Dr. Boris C. Kondratieff. We dedicate this volume to his memory and provide an obituary in this volume.
