Donner Lake, California

*A native of Europe, the German yellow jacket reached Wisconsin in 1979. Its arrival sparked a sharp increase in emergency room treatments for stings. German yellow jackets kill small soft-bodied insects and are aggressive scavengers with a taste for protein and sweet foods. Foragers return to their nest with food, which they feed to adult and larval wasps.
