Rustic Jumping Worm

Distribution

"Amynthas agrestis" is native to Japan and the Korean Peninsula, and was introduced to North America due to increased human activity during the 19th century; it is considered to be an invasive species in the United States. Worms within the genus "Amynthas" reproduce and develop quicker than their European counterparts.

Behavior

The Asian jumping worm follows an annual life cycle. At least six months out of the year, it spends its time in the larval stage, then adults appear between May and June.

Habitat

"Amynthas agrestis" became a problem in the United States, specifically the Southern United States, during the 19th century. Concern is increasing about this invasive species.

One of the main concerns is their overconsumption of leaf litter, which impacts the microbial and species diversity of the native soil. Many of these ecological scientists have created ways to control this invasive species. One of the main ways to control "A. agrestis" is controlled burn in grassy fields and some forests. This method removes leaf litter, the main food source for the species, which should thoroughly control its overall population.
