Banana Spiders in Louisiana: Traits, Bites, and Tips for Safety

Banana Spiders are Common in Louisiana

The banana spider is one of the most common large spiders seen in Louisiana. Known by the scientific name Nephila clavipes, these large orb weavers thrive in the warm, humid climate and are often found in gardens, brush areas, and woods throughout the state.

Identifying Features of the Banana Spider

The banana spider has several key identifying features:

Large, oval abdomen that may reach over 1 inch long. The abdomen has a yellow and black pattern that resembles a banana, giving rise to the spider's common name.
Sturdy web spanning 2 to 3 feet, often found in shrubs and bushes.
Females have a legspan reaching up to 5 inches, while males are under half an inch long.

Webs Allow the Banana Spider to Catch Prey

The banana spider constructs an exceptionally strong, golden-colored orb web using silk. The web allows the spider to ensnare butterflies, beetles, grasshoppers, moths, bees, wasps, and other flying insects for food.

Their webs can persist for several weeks at a time. Each day, the resident female banana spider repairs and maintains the web, replacing any damaged sections.

Are Banana Spiders Dangerous?

While menacing in appearance, the bite of a banana spider is not considered dangerous or medically significant for humans. Some key facts about banana spiders and bites:

They have small fangs and cannot easily pierce human skin.
If they do bite humans, they generally don't inject much venom.
The venom is designed to paralyze insect prey, not large animals.
Bites may cause mild pain and redness, but have no lasting effects.

How to Avoid Getting Bit

To avoid bites from a banana spider:

Watch for webs when outside and avoid walking into them.
Use caution when working in gardens where banana spiders may reside.
Resist the urge to touch or handle a banana spider.
Educate children about respecting spiders and not touching their webs.

Interesting Facts About the Banana Spider

In addition to their size and striking web, banana spiders have some other fascinating traits:

Females are 25 times heavier than males on average.
Their golden webs shine under UV blacklights at night.
Banana spiders don't come inside homes, preferring outdoor habitats.
They recycle old webs, eating the silk to regain protein.

The Annual Life Cycle

Banana spiders have a seasonal cycle in Louisiana:

In spring, males reach maturity and seek out female webs to mate.
Females lay several egg sacs over summer, with up to 900 eggs inside.
Young hatch in early fall and feed on insects before winter comes.
Only females can overwinter, hiding in rolled leaves or crevices.

Come next spring, the cycle begins anew as females emerge to spin fresh webs and lay eggs!

Coexisting Safely With Banana Spiders

While startling if you blunder into one, banana spiders are generally harmless to humans going about normal outdoor activities. Some tips for safe coexistence include:

Learning to identify their large webs so you can avoid them.
Not attempting to remove or relocate them once established.
Pruning vegetation well away from the web perimeter.
Ensuring play areas don't harbor banana spider webs.

An Impressive Louisiana Species

So while banana spiders can be initially jarring due to their size, colors, and webs, they are not considered dangerous in Louisiana. With proper understanding and precautions around them, banana spiders can be safely admired for their beauty and master web building abilities!
