The term pollen source is often used in the context of beekeeping and refers to flowering plants as a source of pollen for bees or other insects. Bees collect pollen as a protein source to raise their brood. For the plant, the pollinizer, this can be an important mechanism for sexual reproduction, as the pollinator distributes its

Because accurate identification of different pollen mite species is exacting and microscopic, and several host bees are in commerce and shipped regularly, it is likely that Ch. Krombeini is over-identified. Even experts express reluctance in specifying mites, such as reported in a study of Osmia pumila. [1]
Where the same plants have non-bee pollinators such as birds or other insects like flies, these are also indicated. Pollination by insects is called entomophily. Entomophily is a form of plant pollination whereby pollen is distributed by insects, particularly bees, Lepidoptera (butterflies and moths), flies and beetles.
Two of the subfamilies, Euryglossinae and Hylaeinae, lack the external pollen-carrying apparatus (the scopa) that otherwise characterizes most bees, and instead carry the pollen in their crops. These groups, and most genera in this family, have liquid or semiliquid pollen masses on which the larvae develop.
Pollen itself is not the male gamete. [4] It is a gametophyte, something that could be considered an entire organism, which then produces the male gamete.Each pollen grain contains vegetative (non-reproductive) cells (only a single cell in most flowering plants but several in other seed plants) and a generative (reproductive) cell.
Pollen provides the protein and trace minerals that are mostly fed to the brood in order to replace bees lost in the normal course of their life cycle and colony activity. As a rule of thumb, the foraging area around a beehive extends for two miles (3.2 km), although bees have been observed foraging twice and three times this distance from the ...
Like many other solitary bees, they can often be found nesting in dense aggregations, [4] sometimes numbering many tens of thousands of nests. In parts of the west European range of the species, Colletes hederae are frequently parasitized by the larvae of the meloid beetle Stenoria analis , [ 2 ] which feed on the supply of nectar and pollen ...
