What plants are damaged by the May beetle?

May beetles are still in the larval stage, living in the soil, feeding on the roots of various plant species. An adult, the so-called “imago” feeds on aerial plants, most often leaves, in rare cases – shoots. May beetles can cause no small harm to young plants of fruit, berry, forest trees. In addition, they can damage both garden and field crops. They can feed on birch, oak, maple leaves. Mass years of May beetles can occur, which will entail a complete gnawing of the foliage.
