How Long Do Common Spiders Live?
WouterThere are a wide variety of spiders, and the life span of these creatures depends on the species. The average lifespan of most spiders is a year, but some live for several years. Among the longest-lived species are tarantulas and wolf spiders.
While many people are afraid of spiders, they can actually be quite interesting. There are thousands of different species. Some are extremely common, while others are found in far-flung places. There are even some that are considered delicacies in parts of Asia.
Although the life span of a spider is not very long, there are a few important things to remember. Generally, larger spiders will live longer. They can also survive without food for a longer period of time. Besides, they can get water from condensation or dew drops.
Another factor that affects their lifespan is predators. While most spiders do not eat babies, they do feed on younger spiders. If they are killed, they can self-amputate.
Female spiders can have hundreds of young. The number of eggs produced depends on the type of spider. Some may have only one or two young, while others may produce as many as five or six. Normally, the eggs will take eight to thirty days to develop.
Some spiders may live as long as twenty years. Other animals, like wasps and butterflies, have a much shorter lifespan.
Some spiders, like the barn funnel weaver, are well-hidden and can survive for up to seven years. They construct funnel-shaped webs to trap their prey. Their nocturnal habits allow them to sit on branches during the day and on bark at night.
