Beetlehangers.org

Beetlehangers.org is an online platform designed to harmonize global host–parasite records, focusing on the interactions between the harlequin ladybird (Harmonia axyridis) and its parasitic fungus Hesperomyces harmoniae. This collaborative initiative was built to engage citizen scientists, researchers, and enthusiasts in contributing data to better understand these species and their ecological dynamics.

The platform aggregates information from scientific literature, online databases, and citizen science contributions to offer a comprehensive, up-to-date overview of the distributions and trends of both the host and parasite. Harmonia axyridis has been documented in 86 countries across six continents, while H. harmoniae is found in 33 countries on five continents. The website serves as both a repository and a tool for visualizing spatial and temporal trends, enhancing our understanding of the global reach and ecological impacts of these species.

Beetlehangers.org also emphasizes the potential of citizen science in tracking and studying species interactions, providing opportunities for public engagement and scientific discovery. Future plans for the platform include expanding its scope to encompass other Laboulbeniales fungi and creating a hub for collaborative research and education. By bridging the gap between scientists and the public, Beetlehangers.org exemplifies the integration of technology, research, and citizen science in addressing complex ecological questions.
