Notable Spiders Found in Hawaii
Discover the unique and fascinating Hawaiian Happy-Face Spider, the elusive Kaua’i Cave Wolf Spider, and the striking Golden Silk Orb Weaver. These are just a few of the notable spiders found in Hawaii that make this island paradise their home.
Hawaiian Happy-Face Spider
The Hawaiian Happy-Face Spider makes many people smile. It looks like it has a happy face right on its belly! This tiny spider lives in Hawaii’s forests and is as small as the tip of your pinky finger.
Its shiny back parts come from little bits inside that catch light like crystals.
People love this spider because it shows how special Hawaii’s bugs can be. They changed over millions of years to live in the islands’ different places. The happy-face design helps them hide from birds and other animals looking for a snack.
Next is another interesting creature, the Brown Widow Spider, which also calls Hawaii home.
Brown Widow Spider
The Brown Widow Spider lives in Hawaii, often found in crevices, rotten wood, gardens, and forests. These spiders are known for the comb-like rows of stout, curved bristles on their hind legs.
They are generally timid and inject less venom when they bite compared to black widows. Although there has been a verified report of a Brown Widow Spider bite in Hawaii, they are not among the most dangerous spiders found in the region.
Kaua’i Cave Wolf Spider
Moving from the venomous Brown Widow Spider, let’s talk about the unique Kaua’i Cave Wolf Spider. This intriguing arachnid is exclusive to the Hawaiian island of Kaua’i and inhabits lava caves on the island.
Its blind nature is a result of its cave-dwelling habitat, where it preys primarily on the endangered Kaua’i Cave amphipod. Measuring between 0.39-0.78 inches (10-20 mm), this spider also has an unknown reproductive behavior, adding another layer of mystery to its already fascinating existence in Hawaii.
Golden Silk Orb Weaver
Moving on from the Kaua’i Cave Wolf Spider, let’s explore the intriguing golden silk orb weaver found in Hawaii. These spiders are commonly known as banana spiders due to their distinctive color and shape, attracting curiosity and often misunderstanding.
The golden silk orb weavers, scientifically named Trichonephila clavipes, are large orange and brown spiders with feathery tufts adorning their legs. They can commonly be seen across Hawaii under different names such as giant wood spider or calico spider.
Their unique appearance makes them a notable and memorable part of the Hawaiian spider population.

The Ecological Role of Spiders
Spiders play a key role in maintaining the balance of nature in Hawaii. By feeding on insects, they help control pest populations, which protects plants and crops from being damaged.
This natural form of pest control reduces the need for chemical pesticides, benefiting both the environment and agriculture. Additionally, spiders are an essential food source for birds and other animals, contributing to the intricate web of life in Hawaii’s diverse ecosystems.
The presence of spiders also indicates a healthy ecosystem as their population reflects the condition of their habitat. Studies have shown that Hawaiian spiders closely reflect the properties of their environment through stable isotopes, highlighting their close association with the island’s unique ecosystem.
Tips for Spider-proofing Your Home
Spiders play a vital ecological role. Now, let’s explore some tips to keep them out of your home:
- Keep storage areas tidy and free of clutter to limit hiding spots for spiders.
- Remove spider webs from your home as soon as possible.
- Create a spider repellent using peppermint oil and water.
- Utilize a Hawaiian product called ‘slippers’ to deter spiders from entering homes.
- Seal cracks and gaps in the home to control wolf spiders.
Do Ladybugs Eat Spiders? Exploring Spider Predators
When it comes to spider predators, ladybugs are not one of them. Ladybugs mainly feast on aphids, keeping their population in check. Unlike some other insects, spiders don’t fall under their diet preference.
Spiders usually have a variety of natural predators like birds, wasps, and certain species of ants and beetles. However, ladybugs are not among these predators as they focus on controlling the aphid population.
Therefore, if you’re dealing with a spider issue in your home or garden, relying on ladybugs may not be an effective solution as they won’t target spiders for consumption.
Conclusion
In Hawaii, there are both native and introduced spider species. Some of these spiders can be a bit scary, like the brown widow and the Kaua’i cave wolf spider. However, while there are some dangerous spiders in Hawaii, life-threatening bites are rare.
