Food
The female beetle lays its eggs in the flower buds of the host-plant and the larvae develop within the flowers. Oviposition and feeding damage the buds of oilseed rape and similar Brassicas and may cause the flowers to drop. Both adults and larvae feed on the pollen and nectar in the flowers.References:
