It’s beetle versus bush when a mass of viburnum leaf beetle eggs (dark lump) starts developing under a rough, brown covering left by their mom. Video (one image per half-hour for three weeks) at first shows nothing more dangerous than a casual white mold frosting their covering, but then the plant’s response kicks in and breaks the egg pile. A strong plant defense may have favored beetle egg crowds that even out the fight.
