Colorado Butterfly Monitoring Network (CBMN) is a community science project led by Butterfly Pavilion that harnesses the power of volunteers to conserve Colorado butterflies.

CBMN volunteers observe and count butterflies in open spaces and parks multiple times per season, gathering essential data that land managers can use when making conservation decisions. It’s a fantastic chance to get outdoors and learn about butterflies, while having a positive impact on conservation in Colorado.

If you are a current monitor with CBMN and are in need of assistance, have questions, or need help with identifying a butterfly, please email cbmn@butterflies.org. Additional resources are available here: https://butterflies.org/cbmn-volunteer-resources/

Butterfly Pavilion (Westminster, Colorado) exists to foster an appreciation of invertebrates by educating the public about the need to protect and care for threatened habitats globally, while conducting research for solutions in invertebrate conservation.
