Asian Jumping Worm
Amynthas agrestisAlso known as Crazy Worm, Snake Worm, Alabama Jumper
Asian jumping worms alter forest ecosystems by rapidly consuming organic surface litter and leaving behind dry, grainy soil resembling coffee grounds. When disturbed, adults thrash violently side to side, leap several centimeters, or shed part of their tails to evade capture. Reproduction occurs parthenogenetically, producing tiny egg-filled cocoons that easily survive freezing winters in topsoil and nursery potting mix.
