There a few small solitary bees buzzing around and occasionally settling on the wall. They appear to be red mason bees.
I noticed that occasionally one of the resting bees would be dive bombed by another, chasing the first bee away. This happened on a few occasions.
Later I noticed a couple of pairs mating on the wall.
Due to the brightness of the reflected sunlight, the bees are difficult to distinguish.
I also witnessed one of the pairs being dive bombed by another bee, possibly a male trying to dislodge the male from the mating pair. It did not have any affect.
This was fascinating to observe.
