Oh if they were living there, you'd know it! They also attack fruit trees and grapevines ...and callas, and cannas, and dahlias...uuugggg. But rose blooms are their favorite of course. Well, I guess I can't fault them for that- they've got good tastes
They did fuel my interest in old garden roses because the one time bloomers are finished before beetles emerge.
This is why I often say I live for first flush
