@nanonaturalist I found large black bees. I couldn’t get a detailed shot but they were about 1in to 1.5in long and had a shiny black abdomen
Did somebody say shiny black abdomen?
There aren’t too many species in North America, and the large carpenter bees are in the Xylocopa genus [link to bugguide page]. My friend up above is an Arizona Carpenter Bee (Xylocopa californica ssp. arizonensis). If it’s LARGE and BLACK and SHINY, it’s a carpenter bee!
unleeessssssss it’s a fly
