Firefly Citizen Science Project

Fireflies of Utah

Did you know there are fireflies in Utah?

For many years, our entomologist has been hearing anecdotes from Utahns about occasional firefly sightings. We've been partnering with scientists at BYU to track their populations, using the help of citizen scientists.

Geneticists at BYU are researching the relationships of various species and how the populations in Utah, that are separated by hundreds of miles and many geographical barriers, are related to the Eastern U.S. populations.

What are fireflies?

Fireflies, also called lightning bugs, are beetles and both males and females light up as a way to attract mates and deter predators. The oldest specimen collected in Utah is housed at the Natural History Museum of Utah and was collected in 1929. Fireflies are not new to Utah, but we have much to learn about them. They are most often found in wet habitats from May-June and start flashing around around 9:45.
