Spider Life Expectancy at Life

Spider Life Expectancy. In optimal conditions, spiders can live several years. Many male spiders reach maturity within two years and die after mating.

Spiders and their eggs and young are food for many animals. Lifespans vary, but on average, most house spiders have a life cycle of about a year or two. The life span of most huntsman species is about 2 years or more.

The eggs are wrapped around a silky cocoon and thereafter attached to foliage. Huntsman spiders, like all spiders, moult in order to grow and often their old skin may be mistaken for the original spider when seen suspended on bark or in the house. However, spiders face many dangers that reduce their chances of reaching a ripe old age. Most spiders live about two years, but some have been known to live up to 20 years when in captivity.
