Invasive Jumping Earthworms Spotted

What grows up to eight inches long, is dim with a white band, can jump a foot in the air and is the furthest down the line danger to California's woods environments?

The response is the Asian hopping worm (Amynthas agrestis), an exceptionally portable types of night crawler with a great hunger that was located in the state without precedent for late months.

"These night crawlers are very dynamic, forceful, and have unquenchable hungers," the California Department of Food and Agriculture (CDFA) said in a report.

Consistent with their name, they hop (known to leap off the ground or out of a snare can) and whip promptly while dealt with acting more like a compromised snake than a worm,

In some cases in any event, breaking and shedding their tail when gotten."

A specimen was spotted at a nursery in Napa County in July of 2021. While no further specimens have been reported in California,

The CDFA said it was likely that the species would spread widely throughout the state.

Native to Japan and the Korean Peninsula, the earthworms are considered an invasive species in the U.S. because they did not evolve alongside other species in the country and can, in fact,

Have a negative impact on them, the U.S. Department of Agriculture’s Forest Service explained.

This is because the species – also known as Alabama jumpers, Jersey wrigglers, wood eel, crazy worms, snake worms and crazy snake worms,

Devours the fallen leaves that cover the forest floor and create the top layer of its soil.

While this is standard fare for earthworms, what is not standard is the speed at which the jumping worms devour their leafy food.

They can consume a forest’s entire leaf layer in two to five years, according to CDFA.

Soil is the groundwork of life - and Asian hopping worms transform it," Forest Service specialist Mac Callaham said in a public statement.

As a matter of fact, worms can have such tremendous effects that they're ready to really reengineer the biological systems around them.

They supplant the leaf-layer soil with a dirt made out of worm castings that doesn't give a home to understory plants and is overwhelmed by microorganisms as opposed to parasites, as per CDFA.

This speeds up the change of leaf garbage to minerals and implies that plants don't have as numerous natural supplements to consume.

Since the timberlands currently have less plants and less fortunate soil, they are more in danger from disintegration and illness.

This is particularly an issue for hardwood woodlands that contain maple, basswood, red oak, poplar or birch.
