Although the above says they've been in the southeast a good while, I've not seen any here. According to the article they feed on leaf litter etc, not our plants. This is the only reference to harm caused by them:
"Once established, populations can build quickly. They can out-compete and push out the other earthworms and degrade ecosystems, especially forests and woodlands by stripping the soil surface of protective organic matter."
