Where do Bluegrass Billbug adults typically overwinter?

• A. In the soil
• B. On grass blades
• C. In thatch and surrounding areas
• D. Under sidewalks

Answer: (C)

Bluegrass Billbug adults typically overwinter in thatch and surrounding areas. This is where they seek refuge from cold temperatures and harsh winter conditions. The thatch layer, which is a mix of decaying organic matter and living roots, provides a more stable environment that helps to protect the adults from freezing temperatures. Additionally, being in these areas allows them to be close to their food source for when they emerge in the spring. Understanding this behavior is important for pest management strategies, as it suggests that control measures may be most effective if applied before these adults become active in the warmer months.
