   note: the ladybirds are usually more or less hemispherical in
         form, with a smooth, polished surface, and often
         colored red, brown, or black, with small spots of
         brighter colors. both the larvae and the adult beetles
         of most species feed on aphids, and for this reason
         they are very beneficial to agriculture and
         horticulture.
