I am sorry that I did not get this done earlier- the message somehow got deleted from my e-mail.

Daddy-long-legs are members of the order Opiliones (or Phalangida) in the class Arachnida. They do not produce silk as the so-called daddy-long-legs (or squint-eyed) spiders in the family Pholcidae of the true spiders (order Araneae of the Class Arachnida). However, development is similar in that true daddy-long-legs begin as eggs and after these hatch the baby daddy-long-legs go through several molts to reach adulthood. To be exact, the female may lay 20-600 eggs, depending on the species involved. The baby daddy-long-legs then molt six or seven times after the first molt following hatching. It takes six to nine months for them to reach maturity.
