Thrips are small, soft-bodied, cigar-shaped insects that are just 1/25-inch long. They can be brown, black, or yellow, with some having colored markings. They have narrow, fringed wings, but are poor fliers. Nymphs look similar to adults, but are smaller and wingless. Thrips are hard to detect with the naked eye, and they may hide under leaf litter, in bark, on the undersides of leaves, inside plant buds, or curled leaves. They can leave behind dark deposits, sometimes referred to as “thrips poop,” which are tiny black spots combined with stippled or wrinkled leaves. Thrips can also cause silvery scratch marks on the leaf surface.
