Pollinator or pollen. Female orchid bees act as pollinators, but of flowers other than orchids. Eusocial bees such as honey bees need an abundant and steady pollen source to multiply. Honey bees travel from flower to flower, collecting nectar (later converted to honey), and pollen grains. The bee collects the pollen by rubbing against the anthers. The pollen collects on the hind legs, in a structure referred to as a "pollen basket". As the bee flies from flower to flower, some of the pollen grains are transferred onto the stigma of other flowers. Nectar provides the energy for bee nutrition; pollen
Pollen beetle but pollen is a major part of its diet. Several members of the Nitidulidae are similarly referred to as pollen beetles. In particular, practically all the species in the genus "Meligethes" are called pollen beetles. Of these the most notorious is probably the one now accepted as being properly called "Meligethes aeneus"/"Brassicogethes aeneus". It is called the "Brassica pollen beetle", "Rape pollen beetle" and similar names, because it first became prominent as a pest of such crops in the first quarter of the 20th century. Many species in the family Oedemeridae are similarly called "pollen beetles". For example, the Southern
