Pine tip moth overwinters as a:

• A. Egg
• B. Larva
• C. Pupa
• D. Adult

Answer: (C)

The stage that best survives winter in this insect is the pupal stage. After the larvae finish feeding on the spring-growing pine shoots, they spin a protective cocoon and enter a dormant pupal state in sheltered places like within shoot tips or under bark. This pupal form remains through the cold season and then adults emerge in spring, ready to begin a new cycle. The pupal stage is well-suited for overwintering because it is non-feeding and protected, reducing exposure to freezing temperatures and desiccation while waiting for favorable spring conditions. Eggs would have to endure winter ready to hatch, larvae would still need food and shelter during winter, and adults would need to survive as flying insects in cold conditions, which is less reliable.
