DENVER (AP) - Colorado zoologists are hoping a rarely seen butterfly's appetite for hops will encourage like-minded beer drinkers to generate money to study the insect.
The blue-and-purple hops azure butterfly, or Celastrina humulus, lives along the Front Range between El Paso County and Wyoming. Researchers don't know much about it but know it loves hops, a key beer ingredient.
The Denver Post reports (http://bit.ly/197QdJU) that last fall Colorado Natural Heritage Program biologist Robert Schorr approached Odell Brewing Co. in Fort Collins about a possible collaboration, to see if the region's love of craft beer could generate funding to study the butterfly.
Starting May 18, Odell is introducing a French-style beer called Celastrina Saison. For every bottle sold, the brewery will donate $1 to the Colorado Natural Heritage Program at Colorado State University.
