Of the relative multitude of bugs that feed on cucumber leaves, the leafhopper (Empoasca spp.) is probably going to turn the foliage white. Leafhoppers are little, wedge-formed creepy crawlies normally yellow, green, or brown in shading. These irritations feed by penetrating the leaves with their mouthparts and sucking out the plant liquids. The taking care of movement at first causes minimal white spots or white texturing to show up on the leaves’ upper surfaces.
