  • The ‘furnace ants’ or ‘honeypot ants’ present a very large genus of ants, Melophorus, confined to Australia. Long believed to be megadiverse, some scientists have even suggested that the group may contain ‘well over 1000 species’. However, to this point, only 32 species and subspecies had been described. Scientists Dr Brian Heterick of Curtin University, Dr Mark Castalanelli of Ecodiagnostics Pty […]
