The Firefly Atlas was created to gather detailed distribution data on threatened and data deficient species in North America. Given the large number of threatened and data deficient taxa and the difficulties in accurately identifying many of them, we are prioritizing efforts for 13 species of conservation concern that can be reliably identified in the field or with non-specimen evidence (photos, videos, or measurements of flash patterns coupled with habitat, location, and timing information). These 13 species occur primarily in the Mid-Atlantic, Southeast, and Southwest regions of the United States. To learn more about these focal species and determine if they are known or suspected to occur in your area, check out the species profiles below.
