A LOOK AT THE LIFE CYCLE Show How long do spiders live? This answer can vary depending on the type of spider. There are more than 38,000 different spider species, many of which have very different breeding habits. But despite their differences, there are a few aspects of the spider life cycle that all spiders share. WHAT IS THE SPIDER LIFE CYCLE? Spiders begin their lives in egg sacs. The amount of eggs per sac depends on the type of spider, ranging from one egg to thousands of eggs. Female spiders defend these eggs in different ways. Some carry the sac with them, some leave them in a defensive zone where they can easily protect them, and some leave the eggs to their own fate. Egg development can take anywhere from a couple of weeks to an entire winter season. Once hatched, the spiders disperse by walking away or ballooning. When a spider balloons, it produces strands of silk that form into a triangular-shaped pouch, sometimes called a “kite.” The spider uses this “kite” to be lifted into the air and transported to a new home. To reproduce, a male spider spins a special web to catch his sperm and transfers it to his pedipalps, a second pair of appendages that function as sensory organs. He then goes in search of a female of the same species who is ready to mate. Some spider courtship involves the male performing intricate dances to prevent the female from having her mate as a meal instead. HOW LONG DO SPIDERS LIVE? The spider lifespan can vary as much as the spider life cycle. Most spiders live about two years, but some have been known to live up to 20 years when in captivity. Female spiders tend to live longer than male spiders. Many male spiders reach maturity within two years and die after mating. This is mostly because female spiders eat them; however, there are some species of male spiders that die an obligatory death from the mating process alone. Female spiders have a large impact on the lifespan of their male counterparts. Terminix® can make an impact on any spider lifespan.

In addition, spiders have moveable claws on their feet that grip and release the web’s threads as they walk.  Spiders are invertebrate creatures in the araneae order of the class arachnida in the phylum arthropoda. A spider has up to eight eyes, eight legs and seven silk-producing glands in its abdomen. These glands secrete proteins that are extruded through spinnerets to produce different kinds of silk. Many spiders, particularly orb, funnel, sheet and cob-weaving spiders, use this silk to build webs with which to catch prey. We’ll focus on orb-weavers because their webs are the most recognizable. Their webs are complex nets of strong dragline threads (frame, spokes) radiating out from the center; and elastic, sticky catching threads spiraling into the center. An orb-weaver begins its web with radial and framework threads using dragline silk, providing a foundation upon which to spiral the sticky catching threads. The spiders then create an auxiliary spiral to help the radial threads support the spider’s weight as it builds. Next, the spider uses, and subsequently destroys, the auxiliary spiral as a guide to create the catching spiral, which it dots with glue. What is perhaps the most amazing part of this hour-long process is that orb-weaving spiders often have poor eyesight and weave using only their sense of touch. The sticky, complex nets of silk used for the catching spiral are effective hunting tools, but have often made people wonder how the spiders themselves avoid entangling themselves in their own webs. Many people believe that spiders have special oils that repel the stickiness of their threads. This, however, has never been proven. Scientists are still not entirely certain how most spiders manage to avoid ending up ensnared in their own trap, but there are a few accepted theories. Spiders can spin different kinds of silk, and not all of their silk is sticky. In fact, in a spider web only the silk used for the intricate catching spirals are dotted with glue, so spiders know which threads to avoid. In addition to producing different kinds of silk, web-spinning spiders also have an extra set of claws on their feet. All spiders have two claws on their feet; web-spinning ones have three. These claws are used to grasp threads and provide traction as the spider moves along. Spider silk itself is interesting to scientists because of the irreversible transformation it makes from a water soluble liquid inside the spider, to a non-water soluble thread outside of the body. The reaction has nothing to do with the thread’s exposure to air once it exits the spider; rather scientists believe it has to do with the act of pulling on the thread that realigns the molecules into a solid form. Scientists are interested in spider silk for manufacturing purposes, specifically the viscid (sticky for catching prey) and dragline (strong for stiff radials and framework) threads. The viscid thread is comparable to rubber in elasticity, but has more strength. The dragline thread is comparable to steel and Kevlar® (bulletproof material) in stiffness, but is more elastic and able to absorb higher impact. What makes spiders truly unique in their silk-producing abilities is that they are the only animals that use this silk for multiple purposes. Their multiple silk glands each produce different kinds of silk to aid in mating rituals, create shields for protection from predators, encase their eggs and, of course, weave webs.

In reality, the silk threads can last hours to weeks without rotting.
Do spiders ever leave their webs?They can build webs quickly and easily. Spinning a new web takes less than one day. Although behavior varies depending on the type, common house spiders will usually abandon a web that isn't catching enough food. The abandoned web that is left behind is what you may call a cobweb.
Do spiders build a new web every night?As a result the webs are often rebuilt every night – an operation requiring the manufacture of some 20 metres of silk. To recycle the amino acids that make up the silk proteins, some orb-web-spinners ingest the silk as they systematically dismantle their damaged webs.
How often do spiders redo their webs?While some spiders are known to build intricate webs, others craft their webs from disorganized collections of silk. Additionally, some species of orb-weaver spiders build new webs every day and dismantle it at the end of each night. However, there is no evidence that spiders also consume their own webs.
