Has anyone seen this before? I was pruning a badly frost damaged bougainvillea and kept hearing loud buzzing. I thought it was just a carpenter bee but saw these going in and out of the holes in the bougie's trunk.

There were at least four of these and I was at a loss to determine what type of bee it was. I never saw these large amber colored bees before!
Then I saw a typical black carpenter bee, yep, same size and shape as the amber bees, just shiny black. Then it landed on the end of one of the bougie branches where one of the amber bees was and they began feeding each other! So here are the two bees, a black and an amber colored carpenter bee, swapping spit!

They are obviously the same species of bee, but just different colors. Upon further research it turns out the amber colored bees are males (which can't sting) and the black ones we typically see are females (which can sting). So it looks like I have a colony of carpenter bees in this bougie stump that I was going to remove to make room for other plants. Now what?
