What is the primary difference between the egg sac and the silk retreats spun later by nymphs/adults?
Answer
The egg sac is strictly for reproduction, while retreats are temporarily used when preparing to molt
The egg sac is solely for protecting the developing offspring, whereas the temporary silken sacs, or retreats, spun by nymphs and adults serve the critical function of enclosing the spider while it prepares to shed its skin.
