Genus Delta

It's been a long time since I last saw this yellow wasp. This small wasp has a very unique coloration, but I suspect its population is declining in my area, and it's now very rare and hard to find. It usually flies around my house and often lands on wild plants or grass,and it's been a long time since I saw it. The one who managed to find this wasp was actually not me but my friend, at that time he was playing at my house and when he wanted to go home, suddenly he saw this wasp flying above a flower in front of my house, then he called me and I immediately approached him. this wasp was on top of the wood and I immediately tried to take a picture of it.

Luckily, I managed to photograph this wasp in one attempt, the wasp did not fly away and let me photograph it, my mistake at that time was when I wanted to try to get the macro lens closer to the wasp so that it would fly away.
