Blue Banded Bee
This specie of bee is very active during daytime that you cannot caught it staying on one place. And I don't have a photo of it during the day, yet.
When I was about to call it a day on one of my macro outing, I noticed a group of flying bugs hanging on a long root a plant. I thought they were flies as I used to see them but I was amazed when I saw these creatures finding their place on the single root. They flap their wings and wiggle their feet when someone tries to land on their place.
I saw this lone bee on the other side of a small branch of the same plant where the other bees are staying. They grasp the stem of the tree using their mouth.
