Scientific Classification

Phidippus Californicus

Physical Description and Identification

Adults

  • Size: Male: 0.7-1.1 cm (0.27-0.43 in) Female: 1.2 cm (0.47 in)

Phidippus Californicus Size

  • Color: Their bodies and limbs are black, with bluish-green mouthparts and a bright red abdomen with a black stripe running through its middle. There are two tiny white spots between the red and black parts of the abdomen.
  • Other Characteristic Features: They mimic mutilid wasps as a form of aposematism, deterring predators from eating them.

Eggs

Female spiders lay 2-3 successive batches of eggs, with each consecutive clutch containing fewer eggs. Around 40 spiderlings emerge from the first, 30 from the second, and very few from the third batch of eggs.

Spiderlings

Spiderlings are brownish-gray with a red abdomen covered with various markings. They hatch after 3 weeks and become self-sufficient after the first molt takes two weeks.

The Web

Phidippus californicus do not use webbing for hunting their prey, instead pouncing when the opportune moment arises.

Are Phidippus californicus Spiders Venomous?

Yes, Phidippus californicus Spiders are venomous. They use their venom to catch small insects to eat, but it’s not very strong for humans.

Can Phidippus californicus Spiders Bite?

Yes, Phidippus californicus Spiders can bite. They’re usually busy jumping around, but if they do bite, it feels like a small pinch and isn’t harmful for most people.

Ecological Importance and Behavior of Phidippus californicus

As predators, Phidippus californicus spiders play a critical role in controlling insect populations, which aids in maintaining ecological balance. Their hunting strategy helps to regulate pest species within their habitats, contributing to the health of the ecosystems in which they live.

Natural Predators: These spiders face predation from birds, larger spiders, and other insectivores. Such predation is an integral aspect of the natural control of their populations and maintains the balance of the ecosystem.

Prey-Predator Dynamics: The interaction between Phidippus californicus and its prey involves a complex dynamic where the spider serves as both hunter and hunted. This dynamic is essential for the stability of their ecological community.

Relationship with Humans: Phidippus californicus spiders are generally harmless to humans. While they are venomous, their bites are typically not medically significant and are compared to a small pinch. They are often unnoticed by humans due to their reclusive nature and preference for living in less disturbed areas.

Did You Know

  • The American entomologist husband-wife duo George Williams Peckham and Elizabeth Maria Gifford Peckham first described this species in 1901.

In summary, the Phidippus californicus spider is an integral species within its natural habitat, contributing to the control of insect populations and serving as a food source for other animals.
