WATCH: Huge 'Joro Spiders' from East Asia invading US

Joro spiders are making their way to New York.

The Joro spider, scientifically named Trichonephila clavata, originates from East Asia (typically from Japan, China, Taiwan and South Korea) and is known for its web-weaving abilities and distinctive appearance.

A female Joro spider can span eight to 20cm with its legs spread – bigger than the human hand. Female Joro spiders typically have yellow bodies while the male spiders, which are smaller, are muted yellow and black or brown.

The spiders first appeared in the southern state of Georgia a decade ago and have been slowly migrating northwards.

Scientists say they could move into the Great Lakes area, the northeastern US and Canada in the coming months or years.

According to the nonprofit group INaturalis, the Joro spider has been spotted in Maryland, West Virginia, Tennessee, North Carolina and South Carolina. It has also been seen in the south-central state of Oklahoma.

These spiders are venomous, but their bites are not lethal, and their fangs are too small to puncture human skin.

Like any invasive species, scientists are worried about their impact on crops and trees, but how Joro spiders behave on farms is still a subject of study.

The Joro spider's lifespan is roughly one year.

In most instances, they can be safely ignored, and treated as a nuisance rather than an infestation.
