Against all odds, fireflies find love here in Utah. Out at places like Firefly Park in Nibley, you can watch these dazzling lanterns dance and bounce, starting around early June. Watching these fireflies is magical, even more when you know what it took for them to glow each night.

The first challenge a firefly faces is finding a good wet habitat out here in arid Utah. Finding dark, wet habitat can be tough, but somehow fireflies have done it and have done so in Utah since potentially 1929. Once a firefly finds a good spot, now they have to find each other. Doing this requires precision and chemistry. In their abdominal lantern, the enzyme luciferase must hug both luciferin and a molecule of energy tightly to help combine their parts. Then luciferin combines with oxygen to form the energetic Oxyluciferase. Much like a kid with too much candy, Oxyluciferase is now desperate to release some energy before it’s too much. It does this by releasing a light-emitting photon and we see the magic before our eyes. As if creating light inside one’s body wasn’t tough enough, now they must attune their signal to their species and find each other. Each species has a unique Morse code of light they need to blip in order to find each other.

Now, let’s say a firefly makes it to a marshy habitat and they meet the love of their short 3-week life, now the romance can begin. Males and females copulate for hours, remaining still and stuck end to end. During this time, the male gives the female what’s called a nuptial gift full of protein along with his sperm. If that isn’t romantic, I don’t know what is! The females will store this gift and digest it over several days to help her get the protein to lay her eggs. Once laid, these eggs will take between a few months to 2 years to become adults where they will light their heart out to repeat the process.

For me, thinking about all the chemistry involved, both molecular and romantic, is moving. I hope we can protect their light for generations to come.

Hi, My name is Christy Bills, I am the entomologist at the Natural History Museum of Utah.

I am excited to talk about the Utah Firefly citizens science project. A lot of people are surprised to know that we have fireflies in Utah, but we actually have them in 20 of the 29 counties, that we’ve discovered so far. People are often surprised that they’re here, and they think that they’ve just arrived but they haven’t. They like to live in marshy areas, and they are only adults from late May to early July, so that’s why people often don’t see them, because people aren’t usually recreating in marshy areas.

The firefly citizens science project asks people to report when they see them to the museums website, and that allows us as researchers to know where they are so we can track their activity. We’ve been collecting data on them for 4 or 5 years and learning more about them over that time period.

I’ve actually gone through old newspapers that have been digitized online, and looked for any reference to fireflies or lightning bugs, and I have found zero reference dating back 100 years. However, when you actually talk to people in rural communities who have pastures and farms, it turns out anecdotally a lot of people know about them. This is a really wonderful way of people bridging the academic rural divide, and finding out that people in these communities have a wealth of knowledge that we can draw from, and they’ll say, “Oh yeah my grandpa always had them in the orchard,” or “We always knew that they were there,” so it turns out people always knew about them. Not a lot of people, but enough people.
People have anecdotes about knowing about them in urban areas, where there are clearly not anymore because of development and light pollution. That helps us also know what factors make them go away.

More information about the project is available, at NHMU.UTAH.EDU/fireflies.

I’m Christy Bills and I’m wild about Utah.
