The "Law of Unintended Consequences" Strikes Again!

Bugs!:

"The multicolored Asian ladybeetle was discovered in Wisconsin in 1994. It got here after working its way west and north from the southeast. The bugs were introduced to the United States in 1916 as a biological control for pecan aphids."

Having grown up in Oshkosh, WI on beautiful Lake Winnebago, I learned to live with another "unintended consequence" - the lake fly! Meant to feed the fish - especially sturgeon - in the early 20th century, a professor at the university introduced these USELESS insects to the lake in 'small' amounts. Now they turn homes black during the two separate, week-long invasions!
