horntail -  Chipera Prairie, Winneshiek County, Iowa, USA June 27, 2022
I have not seen a horntail like this one before. I looked at different horntails for a possible match and settled on a male Urocerus albicornis as the most likely possibility. However, I only have this one photo to compare, but I hope the key characteristics are still visible to determine its identity.
