Conservation Needs
  • Because this is a relatively newly described species, we need to know more about its distribution. Report sightings of any fireflies you see 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.
