À propos de ce contenu audio

 Joro spiders, scientifically known as Trichonephila clavata, are a species of spider that has been gaining attention due to their recent spread in the United States, particularly noted in Pennsylvania. These spiders are originally native to East Asia, including Japan, China, Korea, and Taiwan. They have been noted for their distinctive and brightly colored bodies, with females notably larger than males. Female Joro spiders can have bodies around an inch long with leg spans that can reach up to four or five inches.

These spiders are part of the golden orb-weaver family and are known for their impressive and sizeable three-dimensional webs which can sometimes span several feet in width. The name "flying spiders" that is sometimes used in media reports can be misleading as these spiders do not actually fly. Rather, the term might derive from their ability to glide effectively in the air through a process called ballooning. Ballooning is a method used by some spiders to travel through the air using their silk to catch the wind, which can make it seem like they are flying.

Contrary to some dramatic headlines, Joro spiders are not considered dangerous to humans. While they are indeed venomous, like many spiders, their venom is not harmful to humans and is primarily used to subdue their prey, which typically consists of small insects. Bites from Joro spiders are extremely rare and typically result only in minimal, if any, symptoms.

Their appearance in novel areas such as Pennsylvania is attributed to their invasive character. These spiders can inadvertently travel long distances by hitchhiking on vehicles or in cargo, which contributes to their spread. Ecologists are closely monitoring this spread due to the potential implications for local ecosystems. There's a concern about how they may compete with native species, although they could also bring certain benefits, such as controlling pest populations.

Given their recent spread and the attention it has garnered, local residents in newly affected areas are advised to educate themselves about these spiders. Understanding that Joro spiders are not a significant threat to human health is important. However, their impact on local ecosystems continues to be a subject of ongoing research and observation by scientists aiming to understand the full implications of their presence in new environments.
