Formica argentea

Formica argentea

Formica argentea (the silver/grey ant) is a frequent host species for the 'slave-raiding' ant Polyergus breviceps (red). Here, I have disturbed a hibernating nest in early spring. The red Polyergus are slow to wake, but their skittish captives are active earlier in the season and come to life. Sagehen Creek Field Station, California, USA
