Army worms in Atlanta, Georgia are destructive lawn pest, earning their name due to the way they travel in small insect groups consuming the turf stand in their path!  These little guys may only have a life cycle of about 28 to 30 days but boy can they do some damage in a short period of time.  The adult army worm is a nocturnal moth active during humid, warm summer evenings.  The adult female lays her eggs in masses of 50 to more than 100 on the grass blades.  The eggs hatch over the course of a few days and begin feeding immediately on the turf foliage and tender stems.  As the larvae increase in size they will feed for two or three weeks on your turf stand.  In severe cases the larvae can cut the entire turf stand down to ground level, leaving nothing but brown circular patches.   During the day the army worm larvae will stay closer to the soil surface in the shade.  The larvae Burrowing 2 to 8 centimeters down into the soil, the larvae begin the pupate stage, which last about 9 days.  Using soil debris, leaves and silk, the army worm assembles a loose cocoon over their body preparing for their next stage.  After a preoviposition period of three of four days the adult female will emerge and lay her eggs and continue to do so for the next four to five days.  The adult army worm will live anywhere from 7 to 21 days and the vicious life cycle of army worms in Atlanta, Georgia begins again!
