Researchers analyzed the diets of invasive Joro spiders and native orb weavers. They found that the two species do not compete for food. A study compared the stomach contents of Joro spiders and native spiders, revealing distinct diets. The analysis involved DNA fragments from Joro spiders and stomach content from native orb weavers.

The study's findings contrast with previous suggestions that Joro spiders could harm native spider populations. Instead, native spiders maintained their usual diet even when Joros were present.

Further details about the study are available, including the methods used to analyze the spiders' diets and the implications of the findings.
