United KingdomA study published in PLOS ONE analyzed the diets of over 200 Joro spiders from 33 locations in Georgia and South Carolina, comparing them to native orb weavers. Researchers examined the stomach contents of both species and found that Joro spiders consume a wider variety of insects, including 26 species not typically eaten by native spiders. The study suggests that Joro spiders do not directly compete with native orb weavers for food, as native spiders maintain similar diets regardless of Joro presence. While Joro spiders build large, conspicuous webs and occupy significant space, the research indicates they are not significantly displacing native species. Concerns about Joro spiders preying on monarch butterflies were addressed, as the study found minimal consumption of butterflies. Researchers emphasize that Joro spiders primarily feed on pest insects, which could potentially benefit agricultural areas.
