- Nymphs and females are covered by a white waxy turtle-like shell which is 1/16-inch long.
- They have piercing and sucking mouthparts.
- Males are rarely seen.
Biology and Habits:
- They overwinter as black eggs attached to the host plant.
- The eggs hatch in late winter and early spring; the nymphs mature into wingless females, and in 1 to 3 weeks begin laying 1 to 8 live nymphs per day.
- In late summer some nymphs develop wings and fly to other plants.
- In the fall some nymphs mature into males which mat with females which begin producing eggs.
- There are 5-20 generations per year.
- Stunted growth which results from scale sucking juices from the leaves and stems.
- Damage is most severe during dry conditions; large areas of damaged turf may die.
