| Commentary/Habitat: The Green Hairstreak is a recent addition to Nebraska’s butterlfy fauna, having been first discovered in 1991, and now being recorded from four counties. It flies low to the ground, normally in lower reaches of rocky hillsides and ravines, and is easily overlooked, especially in windy conditions. Adults have been observed nectaring on Miners Candle. It has been found on several occasions at the I-80 east rest area west of Sidney ( Cheyenne County). This butterfly (subspecies homoperplexa) was, until recently, considered a subspecies of Callophrys apama, which was recently combined by taxonomists into Callophrys affinis. Keep this in mind when consulting reference material as you may find the subspecies listed under either species. |
