Origin
Amynthas spp. are native to eastern Asia. 

Life Cycle
Mature jumping worms reproduce asexually by depositing egg-filled cocoons into its surroundings. At each first freeze adult worms die with eggs protected in cocoons during winter. Throughout spring months worms hatch where they feed and grow to maturity (approximately 60 days). 

Distribution
Jumping worms arrived to the United States in the 19th century through imported plants, horticultural, and agricultural materials. Amynthas spp. have become widespread in the northeast, southeast, and Midwestern parts of the United States. 

Control Efforts
Prevention of Amynthas spp. is the best method for reducing their spread. Do not buy or use jumping worms in gardens, vermicomposting, or bait.
