Bluegrass billbugs overwinter as adults.

• A. False
• B. Not specified
• C. They overwinter as eggs
• D. True

Answer: (D)

Understanding how bluegrass billbugs survive winter helps explain when you’ll see activity and damage in the turf. They overwinter as adults, not as eggs or larvae. This means adult billbugs endure the cold in protected spots such as leaf litter, thatch, or soil crevices. When spring temps rise, these adults become active, feed on the grass, and lay eggs in the crowns and near the roots. The eggs hatch into larvae that then feed on the roots later in the season. So, the statement is true because the life cycle explicitly has the overwintering stage as adults.
