Plant NameTypeDescription 
ThripsGladiolusInsectGladiolus thrips are tiny insects with feather-like wings, an unusual design in the insect world. They have rasping mouthparts that cause feeding damage characterized as elongated stippling on leaves and flowers, eventually making plant materials appear washed out. Once thrips get into the flowers, they are nearly impossible to control.
