Byturus tomentosus, Raspberry Beetle
Raspberry beetle feeds at the stalk end of the blackberries, raspberries, loganberries. It is mainly a problem on summer-fruiting raspberries.
Though the beetle larvae are pests for Raspberry growers, adults can be found feeding on pollen on a variety of wildflowers. The small adults often congregate within flowers, particularly composites such as Dandelion. (Source: RHS Gardening)
