''Meligethes aeneus'' is an abundant pollen beetle in the United Kingdom. The name now is regarded as being a synonym of ''Brassicogethes aeneus'' (Fabricius, 1775). and accordingly superseded.〔de Jong, Y.S.D.M. (ed.) (2013) Fauna Europaea version 2.6. Web Service available online at http://www.faunaeur.org〕 Adults are about 2–3 mm long, 1–2 mm wide and black with a hint of metallic green. The larvae are up to 3 mm long and white with brown sclerotised plates. ''M. aenus'' is an important pest of oilseed rape.〔Free, J. B. and Williams, I. H. (1979) The distribution of insect pests on crops of oilseed rape (''Brassica napus'' L.) and the damage they cause. Journal of Agricultural Science, UK 92: 139-149〕 It is not known whether it contributes to the pollination of the crop. 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.〔Williams, I. H. (1976), The infestation of oilseed rape (''Brassica napus'' L.) by the pests ''Meligethes aeneus'' Fab. and ''Ceuthorhynchus assimilis'' Payk.
