Already 4 years ago I wrote about this species on my website. Then I watched his invasion of the surrounding plants. Last years it is in considerable quantity. Larvae of this beetle stay in the soil and cause serious damage. Because I grow vegetables on the parcel and plastic tent, so I personally experienced the damage done by these beetles. This year the quantity is intimidating. On the oaks near my dwelling, the beetles ate most of the leaves. The only benefit is for birds, especially jackals, starlings, and sparrows, from dawn to dusk. I hope that their feeding season is approaching at the end of May.
