What Bee is this?

Hey everyone, more bee's, I wasn't lying when I said I really like them. So I have these gazania's that I planted outside my cottage a few months ago and they naturally need daily watering nurturing etc and in doing so I often see the odd cute little visitor.

On this particular occasion it was two, a really small slender bee and an Argentinian black ant. To get an idea of how small the Bee is compare it to the ant in a few of the below pics.

The ant..

The bee...

Now if you look at them both together knowing how tiny an Argentinian black ant is you will notice the size of the bee. It is very slender relative to a normal bee, body shape and coloration almost the same maybe slightly more pale than a traditional 'African Killer Bee' but literally around 1-3 of the size.

An interesting thing about the Gazania is that it only opens when the sun shines on the flower and closes every night.

A coincidental get together?

Which begs the question, what species of bee is this?

I trust you have an amazing weekend.
