Just when you think you’ve become accustomed to the spotted lanternfly invasion, along comes another menace to the ecosystem: the Asian jumping worm. Allow me to introduce you to Amynthas agrestis, also known as “Alabama jumper,” “Jersey wriggler” and the rude-but-accurate “crazy worm.” Unlike garden-variety earthworms, these flipping, thrashing, invasive miscreants are ravenous consumers of humus, the rich, organic, essential top layer of soil formed by dead and decaying small animals, insects and leaf litter in places like forests, plant nurseries and your garden.
