   note: the social wasps make a complex series of combs, of a
         substance like stiff paper, often of large size, and
         protect them by a paperlike covering. the larvae are
         reared in the cells of the combs, and eat insects and
         insect larvae brought to them by the adults, but the
         latter feed mainly on the honey and pollen of flowers,
         and on the sweet juices of fruit. see illust. in
