What Is the Lifecycle of a Spider


On average, spider eggs take about 2-3 weeks to hatch. This timeframe will vary depending on species and the season. For instance, a spider born in winter may not hatch until spring.

Female spiders protect their eggs by placing them in an egg sack and covering it in silk.

How many spiders an egg sac contains will vary per species. A single egg sac may contain a few eggs to several hundred eggs.

Some spider species carry their sac on their back, while others leave the sac in a secure location. Once the baby spiders are ready to emerge from the sack, they’ll rip it open. 

Spiderling/ Immature Stage

Spiderling is immature spiders. They look like an adult spider but much smaller.

A spider is considered a spiderling the minute emerges from the sac.

When spiderlings emerge from the sac, they travel by either walking or ballooning.

Ballooning is an immature spider’s way to travel by flying. While spiders don’t often think of flying insects, they are perfect aviators.

Let me explain. When ballooning, spiders climb up to an elevated area, such as a twig. The spiderling will then raise its abdomen and release its silk in the air. The spider then gets lifted off to the air and carried away by the wind. These trips are typically short, but sometimes they can last for thousands of miles.

Most spiders will molt between five to ten times before reaching full development. As they molt, they will grow new exoskeletons. That said, some species of spiders will emerge from their sac fully developed.

Adult Stage

Once spiders reach the adult stage, they are ready to mate. Adult spiders typically live between one to two years, although females tend to outlive their male counterparts.

Certain species also live longer than others. Black widow spiders can live for up to three years, while tarantulas can live up to thirty years.
