Life Cycle of Jumping Spiders

Egg Stage

The life cycle of jumping spiders starts with the egg stage. After successful mating, the female jumping spider produces an egg sac, which she then carefully guards. The silk-covered sac provides protection to the developing eggs inside and is usually attached to a suitable substrate. The number of eggs within a sac varies among species but can range from a few to several dozen. The female will stay close to the sac, ensuring its safety until the spiderlings eventually emerge.

Spiderlings Stage

Once the eggs hatch, the tiny spiderlings begin their journey into the world. At this stage, they are known as spiderlings and closely resemble miniature versions of adult jumping spiders. Spiderlings are remarkably independent from birth, and unlike many other spider species, they do not rely on their mothers for food or protection. They disperse and start hunting for prey on their own. Despite their size, spiderlings possess all the characteristics and abilities necessary for survival, including the ability to produce silk.

Adult Stage

As spiderlings grow and molt, they progress to the adult stage. The duration of this transformation varies among species, as some reach adulthood within a few weeks, while others may take several months. Adult jumping spiders are sexually mature and ready to reproduce. They continue their hunting activities and exhibit the characteristic traits of their species, such as their specific coloration and courtship behaviors. The adult stage is the period in which jumping spiders engage in mating, communication, and establishing territories.

Adaptive Features of Jumping Spiders

Vision and Hunting Techniques

Jumping spiders possess extraordinary vision, which contributes to their exceptional hunting skills. Their AMEs provide them with high-resolution, color vision that allows them to spot prey from a considerable distance. In addition to their AMEs, jumping spiders have six other eyes known as secondary eyes, which provide them with a wide field of view. The combination of their sharp vision and agile bodies enables them to precisely calculate distances and execute impressive leaps to capture their prey.

Silk and Web-building Abilities

While jumping spiders are not known for constructing intricate webs like other spider species, they do possess silk glands and can produce silk. Silk plays a crucial role in the spider’s life, aiding in various aspects such as creating egg sacs, constructing shelter, or forming draglines that help them navigate their surroundings. Jumping spiders produce silk of exceptional strength and versatility, allowing them to adapt to diverse habitats and situations.

Social Behaviors of Jumping Spiders


Jumping spiders display fascinating social behaviors, including intricate communication techniques. Male jumping spiders, in particular, engage in elaborate courtship displays to attract females. These displays often involve intricate dances, visual signals, and sometimes even vibrations or drumming on surfaces. By using a combination of body movements, postures, and colors, the male spider communicates his intentions and attempts to win the favor of the female.

Mating Behaviors

Mating in jumping spiders is a delicate and complex process. After successfully attracting a female, the male must approach her cautiously, as there is always a risk of being mistaken for prey. To mitigate this, the male performs careful movements and signals to communicate his intentions and establish trust. If successful, mating occurs, and the male may leave a sperm packet for the female to fertilize her eggs. However, not all matings end in success, and in some cases, the male may become a meal for the female.

Fascinating Species of Jumping Spiders

Peacock Spider

One of the most visually stunning species of jumping spiders is the Peacock Spider, known for its vibrant and intricate coloration. Found primarily in Australia, these spiders have the ability to extend flaps on their abdomen, resembling a peacock’s fan, during courtship displays. Males perform elaborate dances, showcasing their brilliant colors to attract females. These tiny arachnids have captured the attention of researchers and nature enthusiasts worldwide due to their dazzling and unique courtship behaviors.

Zebra Spider

The Zebra Spider, also known as Salticus scenicus, is a common jumping spider species found throughout Europe and North America. As the name suggests, these spiders have black and white stripes on their bodies, resembling a zebra. Despite their small size, they are formidable hunters, displaying impressive agility and quick reflexes. Zebra spiders are frequently observed jumping and maneuvering with incredible precision as they hunt for their preferred prey, which includes small insects like flies and aphids.
