Hops Blue Butterfly Conservation and Celastrina Saison

In 2011, Jeremy Siemers and I discovered a few populations of a rare Colorado endemic called the hops blue butterfly (Celastrina humulus). The host plant for this quarter-sized butterfly is wild hops (Humulus lupulus), and the U.S. Air Force Academy has creek drainages with an abundance of hops. Over a few malted beverages, Jeremy and I brainstormed how to develop funding to study this rare butterfly and the fruition was a collaboration with Odell Brewing Company in Fort Collins, CO. In May 2013, Odell developed Celastrina Saison and is donating $1 for every bottle sold to CNHP to study the ecology of the butterfly. Cheers to conservation, creative collaborations, and Odell Brewing Company.
