Look for black and red or black and yellow winged beetles that are 1/2 inch long and shaped like a shield. Adults lay tiny eggs in rows or masses on the undersides of leaves that hatch into nymphs. These look like miniature versions of the adult beetles. Both adults and nymphs may overwinter in leaves or yard waste.
This insect prefers to feed on horseradish, cabbage, cauliflower, collards, mustard, Brussels sprouts, turnip, kohlrabi and radishes. Depending on the food supply, it may also attack tomatoes, potatoes, eggplants, okra, beans, asparagus, beets, and fruit trees.
Harlequin Bugs cause plants to wilt, turn brown and die by literally "sucking the juices right out of them."
