Urban life lets odorous house ants build empires with hundreds of queens
It’s a tale of bright lights, big colonies: Rural ants go wild in the city.
The first systematic lifestyle survey of odorous house ants confirms how much a modest country dweller can change habits in the big city, according to urban entomologist Grzegorz Buczkowski of Purdue University in West Lafayette, Ind.
