Twin Flagged Jumping Spider (Anasaitis canosa)

Dive into the world of spiders and you’ll notice the Twin Flagged Jumping Spider. It’s known scientifically as Anasaitis canosa and is famous for its unique look and quick moves. Spider fans and experts love studying it. Let’s take a closer look!

Twin Flagged Jumping - Anasaitis canosa

Physical Description and Identification

Adults

  • Size: Both male and female Twin Flagged Jumping Spiders are typically compact, with a size range of 3-5 mm.
    Color: These spiders display a primary gray and brown color palette. However, their most distinguishing feature is the prominent white or pale markings, reminiscent of “flags”, present on their legs and body.
  • Other Characteristic Features: The Twin Flagged Jumping Spider is distinctively characterized by its large anterior median eyes that provide almost 360-degree vision and its remarkable agility, being known for its impressive leaping ability and precision in hunting.

Other Characteristic Features

The Twin Flagged Jumping Spider, like other jumping spiders, possesses an exceptional set of eyes that grant them almost a 360-degree field of vision. These eyes not only help them in predation but also play a pivotal role during their elaborate mating dances.

Scientific Classification

Eggs

The exact appearance of Anasaitis canosa eggs remains a bit elusive. Yet, akin to many jumping spiders, they are likely deposited in a protective silken retreat.

Spiderlings

Upon emergence, the young spiderlings resemble miniature versions of the adults. However, they might not fully inherit the trademark markings until reaching maturity.

The Web

Anasaitis canosa diverges from the traditional web-spinning spiders. Instead of crafting expansive webs for prey capture, they employ an active hunting strategy, stalking and ambushing their targets. However, they do utilize silk to fabricate diminutive shelters or hideouts.

Is the Twin Flagged Jumping Spider Venomous?

While the Twin Flagged Jumping Spider does produce venom, it is primarily used for overpowering their prey. For humans, they are not regarded as a threat, with their bite being comparably mild, akin to a bee sting.

Can the Anasaitis canosa Bite?

Yes, like most spiders, the Twin Flagged Jumping Spider is capable of biting. Nonetheless, their default reaction when encountering humans is to evade rather than attack. Bites usually transpire when the spider perceives imminent danger or is inadvertently pressed.

Quick Facts

DistributionMostly found in the southeastern United States.
HabitatThey are versatile, often sighted on walls, fences, and plants.
DietMainly insects and other diminutive invertebrates.
LifespanUsually up to a year.

Did You Know?

A standout trait of the Twin Flagged Jumping Spider is its remarkable eyesight, which is among the best in the invertebrate kingdom. This acute vision aids them in spotting potential prey from afar and is instrumental during their intricate mating displays, where males flaunt their striking colors and unique markings to impress females.
