In Saudi Arabia desert, I saw large black ant-like bugs called "DOMINO BUGS", with white spots. Anyone know¿

Question

These bugs reportedly were encapsulated in plastic and made into sets of "dominoes", sold in hobby shops, etc. I want to buy a set of these. The bugs come with varying spots on each half of their body, and I imagine a complete set would take time to accumulate.
I eye-witnessed these bugs at a desert locale in Saudi, but these critters stayed very far away upon my approach. They built a mound similar to a American black ant, and they were about an inch in lenght. The ones I saw each had varying # of white spots on each side of each half, and I understand that they are actually ground wasps.

Answer 1

It is good you did not buy a set of CAMELS.
What were you doing in SA?
