Integrating eDNA and community science to monitor urban Odonata diversity

open access: yesInsect Conservation and Diversity, Volume 19, Issue 1, Page 84-92, January 2026.
Environmental DNA captured rare and underrepresented taxa often missed by community science observations. Community science revealed adult‐stage observations across a broader temporal window. Integrating both methods improved detection across life stages, seasons, and species prevalence.
