The Xerces Society, in collaboration with the IUCN SSC Firefly Specialist Group and New Mexico BioPark Society, has launched the Firefly Atlas project:

The Firefly Atlas is a collaborative effort to better understand and conserve the diversity of fireflies in North America. Launched in 2022, the project aims to advance our collective understanding of firefly species’ distributions, phenology, and habitat associations, as well as to identify threats to their populations.

Although the Atlas tracks all species described from the US and Canada, we are currently prioritizing efforts for a subset of 13 threatened and data deficient species found in three focal regions of the US: the Mid-Atlantic, Southeast, and Southwest. These priority regions were chosen based upon having a high number of threatened species and/or a high number of data deficient species. – What is the Firefly Atlas?
