Quck answer
The “banana spider” is not a specific species, but rather a common name for several different types of spiders that are found in or near banana plantations. The most common banana spider is the golden silk orb-weaver, known for its distinctive yellow color and strong, sticky webs. However, other spiders, such as the Brazilian wandering spider and the brown recluse, have also been referred to as banana spiders. It is important to correctly identify spiders in order to avoid potential danger, as some banana spider species are venomous and can pose a threat to humans.

The golden silk orb-weaver spider (Nephila clavipes) is commonly referred to as the “banana spider” in the United States. It is the only type of golden orb-web spider native to the North and South American continents. Charles J. Sharp (CC By-SA 4.0)
Have you ever been walking with a friend and come across a large spider sitting in the middle of its web? Your friend might say, “Don’t worry, it’s just a banana spider.” While this may sound reassuring, it’s not entirely accurate. Although your friend may know that the particular black and yellow spider with a zig-zag pattern in its dental floss-like web won’t harm you, it’s important to note that not all spiders called “banana spiders” are harmless. This is where common names can be misleading.
Carl Linnaeus and Scientific Naming
Every living organism on Earth that has been scientifically identified has a unique scientific name, created by Swedish botanist Carl Linnaeus. Linnaeus developed a double naming system and categorized living things based on their form, structure, and habits. However, common names are not as precise and are often based on someone’s personal observation. For example, if you referred to a horse as Equus caballus instead of a horse, people would find it strange. Common names can be confusing, especially when it comes to spider taxonomy. For instance, when referring to a black bear, a scientist would want to know if it’s an American black bear (Ursus americanus) or an Asian black bear (Ursus thibetanus), which live on different continents. It’s important to keep in mind that common names have been used long before scientific names and are still commonly used today.
According to Kristie Reddick, the founder of The Bug Chicks, the use of common names can be complicated because the same name may refer to different species in different parts of the world. For example, the term “potato bug” in Virginia refers to an isopod, while in the western US, it refers to Jerusalem crickets. This can lead to confusion and hinder the identification of organisms. Similarly, the black-and-yellow argiope spider has several common names, including the yellow garden spider, the golden garden spider, the writing spider, the corn spider, and the McKinley spider. The banana spider is often used to refer to harmless species like the yellow and black Argiope spiders, which build their webs in forested areas and lay their eggs on the sides of trees. While their bites may cause redness and mild discomfort, they are largely harmless to humans. However, some species of banana spider, such as the Brazilian Wandering Spider, can be dangerous and cause severe pain.
The Brazilian wandering spider, also known as the “banana spider” due to its frequent appearance in banana shipments from South America and Central America, is an extremely venomous arachnid that hunts prey like a jaguar instead of building webs like other spiders. Its scientific name, Phoneutria, means “murderess” in Greek. The giant wood spider, also a member of the banana spider family, is found in Asian countries like China, Japan, and India, as well as Australia. The female giant wood spider can have a leg span of up to 20cm. There is also a goblin spider genus called Bannana, which is extremely small and found in the leaf litter of Chinese rainforests. While scientists are unsure about their venom, it is unlikely to pose a threat to humans. Despite their reputation, spiders, including banana spiders, are not out to harm humans. It is important to clarify and explain exactly what spider is being referred to when using common names. Sometimes scientific names and common names are the same, as with Tyrannosaurus rex.

Banana spiders are one of the largest spiders in the world, with females growing up to 4-5 inches in body length and males up to 2-3 inches. Their legs can span up to 7-8 inches.
6. Do banana spiders live alone or in groups?
Banana spiders are solitary creatures and do not live in groups. However, it is not uncommon to find multiple spiders in the same area, especially during mating season.
7. Where can I find banana spiders?
Banana spiders are found in tropical and subtropical regions around the world, including parts of Africa, Asia, Australia, and the Americas. They are most commonly found in forests, gardens, and near bodies of water.
8. Are banana spiders good for the environment?
Yes, banana spiders play an important role in their ecosystems by controlling insect populations. Their webs also provide shelter for other animals, such as lizards and frogs.
9. Can banana spiders be kept as pets?
While it is possible to keep banana spiders as pets, it is not recommended. They require a specific environment and diet, and their venom can be dangerous to humans and other animals if not handled properly.
