black-headed strobe ant Opisthopsis rufithorax

These ants are part of a genus containing just 13 species, all confined to Australasia — making them a truly exclusive club in the ant world. The 'strobe' in their common name likely hints at rapid, darting movements or flashing behavior that makes them difficult to track even when you're watching carefully.

Their extreme regional specificity shows how ant diversity can be hyper-localized, with entire genera found in just one part of the world, representing a unique and specialized slice of Australasian entomology.
