A recent introduction to North America, the brightly-colored, palm-sized Joro Spider spins golden webs at higher levels than other spiders.

Native to eastern Asia, the Joro Spider was first found in Georgia in 2014. The size, colors, and novelty of the Joro Spider often draw comparisons to banana spiders. The spider is large enough to cover the palm of an adult's hand (up to 76mm or 3 inches across), and its colors are visually striking. The abdomen is covered in bright yellow and blue-gray stripes, and its long, slender legs have wide black and yellow bands. The belly has a bright red spot on it. Its silk is a yellow-orange color, and it spins golden webs in forests as well as backyard foliage. It is a bit easier to find because webs are created between waist and knee-height.

It has established itself in northern parts of Georgia and has slowly spread its range with some sightings in South Carolina. It can spin its silk into a balloon shape, and use it drift on windy or breezy days to a new location, sometimes over 50 miles away. It remains to be seen how the Joro Spider may affect the local ecosystem. It does not seem to displace native spider populations yet as Joro Spiders have been found sitting in webs that are grouped near each other as well as with different species of spider. Research on the impact it may have in North America is on-going. It feeds on Brown Marmorated Stink Bugs, a pesky insect that native spiders do not catch easily. It is also victim to the same spider predators such as birds and other insects.

The Joro Spider is not dangerous to people. It can bite and has venom, but it is not poisonous unless that person is allergic to this particular species. It can be scared away and is not known to be aggressive. Though relatively new to the continent, entomologists agree that it is here to stay.

* MAP NOTES: The territorial heat map above showcases (in red) the states and territories of North America where the Joro Spider may be found (but is not limited to). This sort of data is useful when attempting to see concentrations of particular species across the continent as well as revealing possible migratory patterns over a species' given lifespan. Some insects are naturally confined by environment, weather, mating habits, food resources and the like while others see widespread expansion across most, or all, of North America. States/Territories shown above are a general indicator of areas inhabited by the Joro Spider. Insects generally go where they please, typically driven by diet, environmental changes, and / or mating habits.
