What Are Twin-flagged Jumping Spiders?

 Twin-flagged Jumping Spiders, also known as Anasaitis canosa, are a species of spiders belonging to the Salticidae family.

They are commonly found in the tropics of America and in Southern Brazil and can grow up to a few millimeters in size.

Their name comes from the unique “twin flags” pattern that can be found on the abdomen.

While the color of these spiders can vary in color, they are all marked with line markings on either side of the abdomen which creates a “flag” pattern.

They make for lively and curious pets and are relatively easy to care for.

What Do Twin-flagged Jumping Spiders Look Like?

Anasaitis canosa has a distinct, flattened appearance and is usually brown or grey in color.

They are relatively small in size, usually ranging between 0.4–0.7 cm (4–7 mm).

Their anatomy consists of eight eyes, two of them being large and prominent, these eyes have silver reflectors and a gold-colored patch underneath.

Additionally, they have a pale stripe running sideways on the edge of the abdomen. 

Another notable feature of the Anasaitis canosa is its large pair of front legs.

At the tip of these front legs, they have black/brown stripes which makes for a unique feature of these spiders.

Benefits Of Using Twin-flagged Jumping Spiders

Twin-flagged Jumping Spiders are a great addition to many different kinds of vivariums, especially desert-themed enclosures.

They have bright colors and interesting patterns, which give any enclosure a unique, visually stimulating look.

Anasaitis canosa is also incredibly active and interactive, often walking around the enclosure and displaying impressive jumping stunts.

Furthermore, they are quite calm and non-aggressive compared to other spider species, meaning that they can even be handled with a bit of skill.

They can also be kept with other spider species in a communal tank since they are not territorial predators.

Finally, they are relatively long-lived when provided with the right conditions and nutrition.

Twin-flagged Jumping Spider Facts

Twin-flagged Jumping Spiders are native to Central and South America and grow to be a few millimeters in length.

They have an outgoing and active temperament and feed mainly on insects, spiders, and other small invertebrates in their natural environment.

Additionally, the webs released by the micro jumper are often wide and thin which contrasts this arachnid from other spider species. 

Finally, what makes the Anasaitis canosa truly unique is its jumping prowess.

They often leap long distances when spotting prey, with some reports citing jumping distances of up to five times their body length.

They can even move sideways and upside-down on flat surfaces such as glass or walls.


Twin-flagged Jumping Spiders are a species of spider native to the southeastern parts of the United States, ranging from the Florida panhandle to Maryland and Virginia.

They are most commonly found in partially shaded, moist environments, and often inhabit woodlands, thickets, and other areas of high vegetation.

They are also found in some urban areas, as well as buildings and other structures.

Anasaitis canosa is most active during the day, with its peak activity period taking place in the early morning hours before the midday heat sets in. 


In the wild, Anasaitis canosa feeds primarily on insects and other invertebrates, including flies, small beetles, and caterpillars.

They use their large eyes to locate and identify prey in the surrounding environment, and their strong legs help them quickly snatch their intended meal.

Unlike their popular relatives, the Jumping Spiders, Anasaitis canosa are able to catch prey in the water, which makes them uniquely adapted to aquatic environments.

They use their silk to create a safety line should they need to quickly retreat from their prey or danger.

Additionally, they rarely scavenge for food and instead primarily hunt for their own meals.


Twin-flagged Jumping Spiders are usually quite docile and easy-going.

Although they can passively defend themselves by biting if disturbed, they’re not known to be aggressive when it comes to humans or other animals.

In fact, they are known to be quite curious and may even come out of their hiding places just to observe their surroundings.

Anasaitis canosa can make a wonderful pet in the right environment as they’re generally shy and unassuming.

When it comes to other animals, these spiders can get along pretty well with bigger spiders such as tarantulas or other jumping spiders, as long as they’re not too aggressive.

They may also get along well with certain geckos and lizards if they’re calm enough, though this varies from individual to individual.

To ensure compatibility, you should always monitor and supervise the interactions between Anasaitis canosa and other animals.


Twin-flagged Jumping Spiders are active and vibrant arachnids that typically have a relatively short lifespan.

In captivity, they will typically survive for a year or two but can live a bit longer in the wild.

They are typically slower-growing and may take up to 6 months or more before they reach full size.

The life cycle of Anasaitis canosa is fairly typical of spiders and begins with courtship and mating.

The female will lay spider-egg sacs, and once the eggs have hatched, baby spiders emerge.

After molting several times, the spider will reach maturity. For male spiders, sexual maturity is typically reached at about the 6th instar.

The female spiders, however, will continue molting for several more cycles before becoming mature.


Twin-flagged Jumping Spiders are viviparous – the female will carry her eggs in a silken sac and the babies will emerge from within the sac as small, fully-formed spiderlings.

Males and females can reach reproductive maturity in about 4 to 6 months.

It’s important to carefully select mates for your spider – you should aim to select healthy specimens with similar color patterns so that you can ensure that the offspring will have strong genes.

When it comes time to mate, the male will approach the female and attempt to groom her, followed by the ritual of vibrating or “drumming” on the web they reside in.

The female will then lay her eggs in the web and guard them until the spiderlings hatch.

After that point, the female will often abandon the babies and their destiny is up to the spiderlings, who must find food and fight off potential predators on their own.

Where To Find Twin-flagged Jumping Spiders

Twin-flagged Jumping Spiders can be found in the wild in tropical, subtropical, and temperate habitats.

They can also be found in human dwellings, where they hunt for food like small insects and other spiders.

They are often found in moist, shady areas, or inhabiting plants or tree bark. 

If you prefer to buy your Anasaitis canosa from a breeder or pet store, you can often find them for sale online.

If buying from a breeder, you should ask questions about the spider’s age, health, diet, and other care-related topics before you commit to purchasing.

Make sure to purchase only captive-bred or collected spiders, and avoid wild-caught specimens as they may not be used to captivity and may not adjust easily to their new environment.

Twin-flagged Jumping Spider Care

To care for Twin-flagged Jumping Spiders, provide them with appropriate tank size and substrate, as well as proper temperature and humidity levels.

Feed them a proper diet of nutritious food sources, and if you’re interested in breeding them, identify the sex and select a breeding partner.

Tank Requirements

When picking out your Anasaitis canosa home, it is important to choose the right tank type, substrate, and other tank decorations for the spider’s needs.

Vivariums made of glass or plastic are ideal for this species and should be relatively tall, with a minimum size of 1 gallon for one spider.

If opting for a paludarium, the ideal pH should be between 6.5 and 7.5, and the water should be soft to medium in hardness.

The temperature within the tank should be kept between 68°F and 75°F, and good quality, the nutrient-rich substrate should be used to ensure the spider’s comfort.

The terrarium substrate should also be kept slightly damp, but not soggy. Lastly, natural light or low-wattage terrarium lighting should be used.
