"What a thousand acres of Silphiums looked like when they tickled the bellies of the buffalo is a question never again to be answered, and perhaps not even asked." -Aldo Leopold
Banded Hairstreak
Satyrium calanus fam. Lycaenidae
Host plant: hickory (Carya sp.)
Dates found: 2 May, 2026
Locations found: Tyson Research Center, St. Louis County, MO
Notes: This was an interesting find. I looked through a number of fresh leaf-roll shelters, finding all of them occupied by a to be identified noctuid caterpillar. In one of these I also found this banded hairstreak caterpillar that was being attended by ants.
Tonight I’m just sharing some photos of a few lovely Lycaenid butterflies that I had the pleasure of photographing this season. The Lycaenidae family is the second largest family of butterflies, with about 6,000 species worldwide. The highlight was the bountiful season that the juniper hairstreak (Callophrys gryneus) had. Prior to this year, I had only seen one or two in a season, usually without my macro rig with me. In a few trips to the glades in Jefferson County this spring, Casey and I had at least two dozen individuals. They are not usually cooperative, but we worked pretty hard to get something.
First up is the afore mentioned C. gryneus.
