At one formicary half a dozen or more young queens were out at the same time.
Many also enter the formicary, and begin to carry off the young brood that are left in it.
Sir John Lubbock chloroformed some Lasius niger belonging to his formicary.
Ants may be readily kept in the schoolroom in an artificial nest or formicary and their life-history and habits closely watched.
Another feature evident in disturbing a formicary is the general harmony in which the individuals of any one colony work together.
