The insects whose overwintering is described with the term flaxseed are which?

• A. Aphids
• B. Hessian flies
• C. Wheat curl mites
• D. Wheat head armyworms

Answer: (B)

The key idea is that some pests survive winter in a protected place within crop residues. The Hessian fly is known for overwintering as a larval/pupal stage inside the seed heads or straw of cereal crops—often described using the term flaxseed because these larvae can live within flax/seed-head debris during the cold months. This sheltered over-wintering allows them to resume development and emerge as adults in spring to lay eggs on new plants. The other insects listed don’t overwinter in flaxseed debris: aphids, wheat curl mites, and wheat head armyworms use different overwintering strategies, such as eggs on host plants or diapause in other habitats.
