Spider Life Cycle
The life cycle of a spider begins when a female lays a large clutch of eggs, sometimes as many as 3,000, in a silken cocoon.
Females of some species will stick around to care for the eggs and the young hatchlings, while others leave the young to fend for themselves.
The eggs hatch into baby spiderlings, which grow into adults over a couple months.
Adult spiders seek out mates through elaborate courtship rituals involving:
- Web vibrations
- Patterns of touches
Among many species, male spiders survive long enough to undergo several sessions of copulation, while the males of other species are devoured by females after mating to ensure she has enough nourishment to produce healthy offspring.
Molting & Life Expectancy
Process of Molting
Spiders have rigid exoskeletons, and they molt several times during development. Molting involves shedding the exoskeleton and entering into a short period of vulnerability while the new exoskeleton hardens.
Each time a spider molts, it grows in size. Some species may undergo over 40 separate molts before reaching adulthood.
Although a large number of spiders never make it past one or two months of life due to predators or parasites, the typical lifespan of a spider is one to two years.
