Flea Beetles– Adults are approximately 1/16 of an inch long; some are entirely black and some are brown-black with lighter markings. The larvae are very small, skinny and white with a black band, and three pairs of legs. They will create numerous round or irregular holes in the plant foliage. The leaves will be covered in holes throughout the entire plant. The leaves will almost always wilt and turn brown before eventually falling off. This, in turn, can eventually weaken or kill the plant. These are chewing insects.
