Female giant silkworm moths will lay infertile eggs within a short time after emergence from the chrysalis if no males are present. From what I know about the females, they have to lay eggs, fertile or not. The saturniids with which I have worked (range caterpillars) lived only 7-14 days as adults and the females started "calling" with pheromones within a day or so. If no males respond within a few days they begin laying. However, your moth may have had some physiological problems if she did not call before laying. Reference: Veenakumari, K, P. Mohanraj, and R.
