  • nests
  • It nests underground among plant roots. (wikipedia.org)
  • Observations inside nests showed that the workers, queen, alates and brood took up stations on the fibrous roots which formed a sort of scaffolding in their nests. (wikipedia.org)
  • During the summer, above some of the nests, workers chewed bits of plant material to produce a papery felt or thatch. (wikipedia.org)
  • scientists
