#thynnidae

Blue Ant (Diamma bicolor), Bttm & mid - females, Top - male, family Thynnidae, Australia

Females are wingless.

Blue Ant (Diamma bicolor), female, family Thynnidae, NE Tasmania, Australia

This is actually not an ant at all, but it actually a species of wasp. The females are wingless, and thus resemble large ants.

The females parastize mole crickets.

Currently unidentified.

Unknown, Thynnidae

Or perhaps Thynnid - these wasps used to be part of the Tiphiid family, but more recent work has elevated them to a full family, at least in some sources. I’m sticking with the Atlas of Living Australia for now, although given that recently did a merger with iNaturalist, then people will need to think about which classification is current (marine molluscs are going to be a nightmare).

Thynnids are almost all parasitoids of beetle larvae, and have wingless females that the male carries around while in flight. I have no idea which genus this one is, but whichever it is is surely famous for their enormous golden muttonchop beards.
