The brilliant jumping spider is a fascinating creature from North America. It’s part of the jumping spider family and stands out among the 60 different spiders in the Phidippus group. In this article, we’ll dive deep into facts and interesting details about this vibrant little spider.
The egg sacs are made of thick silk. A female brilliant jumping spider lays well over 100 eggs per sac after mating, with an average of 135. Most bear only one clutch, though some may lay more.
After 24–26 days, the spiderlings emerge but continue to mature in the cocoon. The first molt takes place 24–28 days once they shed their membranes. 2-3 days later, the spiderlings become active. While not hunting immediately, they spend several hours moving about doing random things before returning to cover. Around 10% build their separate retreats during this period of activity, while the rest do so only after feeding. After the spiderlings leave the nest, the mothers usually die in a few days.
Like other jumping spiders, they are not known to construct elaborate webs. However, webs play an important role in the mating process, as the male will spin a small web to deposit a little sperm. This sperm is then collected by the male which is used to impregnate potential mates.
Yes, Brilliant Jumping Spiders are venomous, but their venom is usually harmless to humans.
Yes, they can bite if they feel threatened, but their bites are typically not harmful to people and are rare.
Phidippus clarus
The Brilliant Jumping Spider plays an essential role in controlling pest populations. Their predation helps maintain a healthy balance in their habitats, especially among flowering plants where they hunt.
Natural Predator: Their life cycle is subject to predation by parasitoid wasps and nematodes, which help control their population and prevent overabundance.
Prey-Predator Dynamics: Their diet helps control insect populations, providing natural pest control which benefits the ecosystem. They use their jumping ability to ambush prey, a method that reflects their role as efficient hunters.
Relationship with Humans: Humans and Brilliant Jumping Spiders coexist peacefully. They are often seen as beneficial due to their diet of insects, and their presence in gardens can aid in the natural control of pests.
| Lifespan | 1-2 years |
| Distribution | Eastern North America |
| Habitat | Flowers |
| Common Predators | Parasitoid wasps like Aporinellus completes and nematodes |
| Diet | Insects, other spiders |
In summary, the Brilliant Jumping Spider is a harmless, beneficial insect predator, vital for ecological balance and pest control.
