It is worth noting that the insect's "diet" includes more than 300 different plant species, ranging from fruit trees to cereals. They are often seen at raspberries, cherries, gooseberries, plums, grapes and other cultures.

Why is it dangerous? An adult insect lays eggs on young shoots of grapes. To do this, the leafhopper cuts the bark with its ovipositor, and lays 6-12 eggs in the resulting incisions. Gradually the damaged shoot dies off, and the grown larvae fall to the ground, where they feed on the juices of the nearest plants.
