What is the spider life cycle?
The spider life cycle progresses through three stages: the embryonic, the larval, and the nympho-imaginal. The time between when an egg is fertilized and when the spider begins to take the shape of an adult spider is referred to as the embryonic stage. As the spider enters the larval stage, it begins to look more and more like an adult spider. It enters the larval stage as a prelarva and, through subsequent moults, reaches its larval form, a spider-shaped animal feeding off its yolk supply. After a few more moults (also called instars) body structures become differentiated. Soon, all organ systems are complete and the animal begins to hunt on its own; it has reached the nympho-imaginal stage. This stage is differentiated into two sub-stages: the nymph, or juvenile stage and the imago, or adult stage. A spider does not become sexually mature until it makes the transition from nymph to imago. Once a spider has reached the imago stage, it will remain there until its death. After sex

The stages in the life of a plant or animal make up what is called the life cycle. The word “cycle,” just like in bicycle, refers to something that is in a circle. The stages in a life cycle repeat from one stage in life to the next, until they come around full circle. Think of the life cycle of a human being. First the baby develops inside the mother’s uterus. The next stage after birth is called infancy, followed by childhood, and then adolescence (the teenage years). Adulthood is the stage at which physical growth of the body is complete. Adults can become mothers and fathers and have children. Old age or the later years are the last stage in the human life cycle.
