Carpenter bee
As far as I know carpenters bees are rare. This year I saw they again in the garden of my mother. It's the second year I saw them here and they were in the same area of the garden as last time. I tried to find the nest but I didn't see a bee flew away. They flew the whole time around the same plant. They were really busy and who knows, maybe there were more and I didn't realized that they alternated.
