True Armyworms survive very cold winters how?

• A. Survive better in cold winters
• B. Does not survive in very cold winters
• C. Only survive in warm winters
• D. Winter survival is unaffected

Answer: (B)

True armyworms are not cold-hardy; freezing temperatures cause high mortality across their life stages. Because of this cold sensitivity, very cold winters wipe out most of the population, so they do not survive through such winters. In milder winters or when they can use sheltered microhabitats, some individuals may persist, but severe cold generally prevents survival. This is why saying they do not survive in very cold winters is the best description.
