Thrips are tiny, long slim insects that cause leaf twisting and silvering leaves and marking of flowers.
Thrips are tiny, long slim insects usually black as adults but pale in younger nymphal stages. There are many different species and they can look quite different depending on species and stage of development. They infest and damage the foliage and flowers of many ornamental plants, vegetables & fruit crops. Thrips may also infest bulbs in storage.
With Thrips you get leaf twisting and silvering leaves and flower thrips will cause discolouration and marking of flower petals. They usually feed along the mid-vein area of the leaf. Thrips are likely to be a problem in a warm dry, sheltered environment.
