The insects pulling the edges of the
caves together; then others trimmed
md fitted the edges, and finally a
'eam was made by fastening the
sdges with silky thread, yielded by
arvae of the same species which the
carried in their mandibles,

method of working. According to
Ridley, the sewing ants pass the
larvae like shuttles
through holes in the edges Of tho
caves
