Weevil in the genus Sphenophorus (likely Sphenophorus cicatristriatus, the Rocky Mountain Billbug): This rather large species of weevil feeds upon grasses and is considered a pest of Kentucky blue grass in parts of Rocky Mountain region and the Northern High Plains. So …if you are someone who maintains an immaculate lawn or owns a golf course, you might not be happy to find this insect. But we love it all the same. Photo by Morgan McNeill on 5/20/18 in Lolo, MT.
