Fireflies are a rare sight in Colorado. Scientists at the Butterfly Pavilion have a plan to change that

Scientists with Butterfly Pavilion's Firefly Lifecycle Project examine fireflies they've collected at night. The project marked a milestone this summer by being the first to successfully raise a firefly through its full life cycle entirely under human care.

For many of us, fireflies are synonymous with childhood wonder. We chase them on summer evenings, catch them and gently put them in a jar – with plenty of holes poked in the lid, of course.

But if you grew up in Colorado, you may have never experienced that particular wonder. You may not realize that Colorado even has native fireflies. Because of development and pesticide use destroying their habitat, it’s difficult to spot these tiny beetles glowing along the Front Range.

Scientists with the Butterfly Pavilion in Westminster hope to change that.

Eight years ago, they began a program called the Firefly Lifecycle Project that set out to completely raise a firefly from egg to adulthood – something that had never happened in a lab setting before.

This year, a female firefly raised entirely under human care at the Butterfly Pavilion, laid eggs. In July, one of those eggs hatched, and several more of them have done so in the weeks after.

To learn more, we reached out to Malaney Dodson, Animal Well Being Coordinator for the project, and Rich Reading, VP of Science and Conservation at Butterfly Pavilion.

They spoke with Erin O’Toole about what made this such a milestone for insect science, and how it might set the stage for Colorado evenings filled with fireflies.

KUNC's In The NoCo is a daily slice of stories, news, people and issues. It's a window to the communities along the Colorado Rocky Mountains. The show brings context and insight to the stories of the day, often elevating unheard voices in the process. And because life in Northern Colorado is a balance of work and play, we celebrate the lighter side of things here, too.
As the host of KUNC’s news program and podcast In The NoCo, I work closely with our producers and reporters to bring context and diverse perspectives to the important issues of the day. Northern Colorado is such a diverse and growing region, brimming with history, culture, music, education, civic engagement, and amazing outdoor recreation. I love finding the stories and voices that reflect what makes NoCo such an extraordinary place to live.
