The "kudzu bug"

YouTube link. 

Kudzu is an amazingly prolific invasive plant that has been devastating large areas of farmland, fields, and woods in the southern United States.  When it first arrived, it spread uncontrollably because it had no natural enemies.  Now, one has been found - a beetle that arrived as another accidental immigrant.

But the new arrival is a mixed blessing, because it also eats other legumes, including soybeans.  This video was prepared by entomologists at the University of Georgia College of Agricultural and Environmental Science.
