What generally happens to most garden spiders encountered in temperate gardens as winter approaches?
Answer
The adults die off after the first hard frosts, leaving behind overwintering egg sacs
Most garden spiders in temperate gardens are annual, meaning they live only for one season. They die when the first hard frosts arrive in the fall, but the female spiders secure egg sacs onto sturdy stems or under leaves to ensure the next generation survives the winter.
