Seasonal development and life cycle—Grape mealybug

Grape mealybug life cycle

In summer, first-generation crawlers move out from bark to infest fruit and foliage mid-June to mid-July. Some females mature in late August to September and lay eggs on fruit; most return to old wood to lay overwintering eggs. In early spring, crawlers move from bark to new shoots.
