I was beginning to wonder if I was going to see any more Bombus pensylvanicus here this year and then yesterday evening I saw a large one stopping to check out the Clematis reticulata, and there it was this morning. This plant has been a favorite here from what I’ve observed over the years.

I would really appreciate help with this identification! This picture was taken at Farm Stand a popular place to go and pay to pick flowers in Branford, Fl. As I started down the rows it didn’t seem like much activity then about half way down I began to see honeybees and Bombus impatiens. When I saw this bee I at first thought it might be a Bombus pensylvanicus it wasn’t till I got home and starting looking through the videos I was changing my mind and wondering if this could be a fly? There were three different bees suggested. In one picture it appears to have a very short antenna and the eyes seemed strange so that’s what made me think it might be a fly. However in another picture the antennas seemed more normal.
Any help appreciated!
