Activity Period and Flash Signal
Adults are active in June and July and give off single yellow-green flashes at uncertain intervals.
The belted firefly has a very small range in Maryland and Delaware, and it appears to be quite rare. Despite extensive survey efforts and examination of museum collections, it has been documented from only five counties.
The belted firefly is found in moist lowland areas in hardwood forests and isolated freshwater forested ephemeral wetlands of the mid-Atlantic coast.
This species is threatened by habitat loss and degradation due to urban development and sea level rise.
- We need to know more about the distribution of this species. Report your firefly sightings from the Delmarva Peninsula of Delaware and Maryland to iNaturalist, or consider participating in Firefly Watch!
- Turn off your outdoor lights at night so the lights of this firefly aren’t diminished by light pollution. You can read more about firefly-friendly lighting in our fact sheet.
- Avoid pesticide use, which could harm this firefly, its habitat, or its prey.
- More research on population size and trend, habitats and ecology, and threats is needed for this species.
