They are ruining our wine.
This type of ladybug has been spreading rapidly across the Midwest because some tasty new prey -- the invasive soybean aphid -- has also become widespread. Winemakers report greater concentrations of ladybugs in their vineyards and on harvested grapes. Apparently the bugs are being mixed into the fermenting grape juice by accident.
This is unacceptable.
I say: all corn, all the time. Do it for the grapes.
