Anthlered Wasp (Eucharitidae)

I got to say that was my first time finding this insect. I did not expect I found it around the meadow as it was a very small insect which troubled me to see clearly. However, I had to make sure about what insect I just took. After taking a shot, I was surprised to see this creature with a unique look. Wondering about its name, I come across the internet and it appears to be called Anthlered Wasp, also called Eucharitid wasp belongs to the family Eucharitidae, specialized parasitoids of ants that usually found in meadow or bush.
