Joro Spider Invasion Wreaks Havoc on South Carolina's Native Ecosystems

According to recent reports, experts are sounding the alarm about a rapidly growing Joro spider infestation in Upstate South Carolina. The Joro spider, an invasive species native to East Asia, was first introduced to the Southeastern United States around 15 years ago and has since been wreaking havoc in the region.

Since the Joro spider's initial documentation in South Carolina in 2018, its populations have exploded, with the infestation becoming particularly severe in the northwest corner of the state. The female Joro spiders are easily identifiable by their unique yellow markings and pink patterns, while the smaller male spiders are typically found in the females' golden-colored webs.

While the Joro spider is not harmful to humans or pets, it poses a significant threat to local pollinators and native spider species. Experts have observed a concerning decline in the populations of native orb-weaver spiders, which play a crucial role in controlling pests and contributing to the overall ecosystem balance. The invasive Joro spiders are outcompeting these native species for resources, leading to a concerning loss of biodiversity.
