Two spotted spider mites overwinter as which life stage?

• A. Adult females
• B. Eggs
• C. Larvae
• D. Adult males

Answer: (A)

Overwintering refers to how a pest survives cold months so it can rebound when conditions improve. For the two-spotted spider mite, adult females persist through winter in protected spots such as leaf litter, under thatch, or within crevices. These females are already mature and have energy reserves, so they can resume feeding and start laying eggs as soon as temperatures rise, giving the population a rapid start in spring. Eggs, while also part of the life cycle, are more vulnerable to desiccation and freezing and would take longer to rebuild populations since they must develop through immature stages before reproducing. Males and larvae don’t provide the same reliable overwintering stock, so the stage best suited to survive harsh conditions and kick off new generations is the adult female.
