Westminster, Colo – Aug. 27, 2020 –Colorado’s Butterfly Pavilion proudly announced today the emergence of three Mountain Emerald Dragonflies, thought to be the first of their kind to be reared from eggs to adulthood under human care. The three males, dubbed Larry, Moe and Curly, represent three years of work by Butterfly Pavilion researchers, as well as the all-important first step in a three-step process to save endangered Colorado dragonflies.

In addition to helping manage mosquito and other insect populations, dragonflies are an important “indicator species” whose presence signals overall health of wetland ecosystems. While the Mountain Emerald Dragonfly isn’t imperiled, it is a close relative to the Hudsonian Emerald Dragonfly, which is.

“Butterfly Pavilion will be able to take what we’ve learned rearing Mountain Emeralds and transfer that knowledge to helping save the Hudsonian Emerald,” said Sara Stevens, Butterfly Pavilion’s Aquatics manager and the lead researcher on the study. “This proactive approach to conservation sets us up to have a large toolkit to help other species.”

Butterfly Pavilion’s three-stage plan for breeding dragonflies is:

  • Rear as many Colorado species of dragonfly from egg to adulthood as possible and release them back into the wild
  • Get two of these adults to successfully reproduce
  • Rear those eggs to adulthood successfully

“Rearing these dragonflies under human care represents an important advancement in the research and conservation of these important and charismatic animals, and demonstrates Butterfly Pavilion’s leadership,” said Richard P. Reading, Ph.D., Butterfly Pavilion’s Director of Research and Conservation. “Our goal is to breed and rear dragonflies to release back into the wild, as well as to display at Butterfly Pavilion. This is another example of Butterfly Pavilion working to protect our ecosystems here in Colorado, as well as the rest of the world.”

Dragonfly breeding is just one of the many programs and projects Butterfly Pavilion manages all over the world, making a global impact in invertebrate conservation. Active projects include: Parnassian Butterfly conservation in Mongolia; managing protected areas in Saudi Arabia; butterfly farming in Indonesia; and reducing human and elephant conflicts through the use of honey bees in Tanzania and Nepal. Domestically, Butterfly Pavilion manages numerous citizen science programs that include butterfly and dragonfly monitoring, as well as open space habitat restoration to better support pollinators.

Community members interested in supporting these programs can make a tax-deductible donation to Butterfly Pavilion’s Resiliency Fund, or give directly to the Research and Conservation Department. Those interested in joining a citizen science program can find more information at Butterfly Pavilion’s website.
