Macropis nuda is a ground nesting, univoltine bee native to northern parts of North America. Thus, this species cocoons as pupae and hibernates over the winter. The species is unusual as it is an oligolectic bee, foraging exclusively for floral oils and pollen from Primulaceae of the species Lysimachia ciliata.
Few flowering plants self-pollinate; some can provide their own pollen (self fertile), but require a pollinator to move the pollen; others are dependent on cross pollination from a genetically different source of viable pollen, through the activity of pollinators. One of the possible pollinators to assist in cross-pollination are honeybees.
Plants fall into pollination syndromes that reflect the type of pollinator being attracted. These are characteristics such as: overall flower size, the depth and width of the corolla, the color (including patterns called nectar guides that are visible only in ultraviolet light), the scent, amount of nectar, composition of nectar, etc. [2] For example, birds visit red flowers with long, narrow ...
It is believed that because solitary bees have very large, lipid-rich eggs the pollen provides the lipids and amino acids required for making these eggs. Pollen consumption is larger in younger females, and primarily occurs in the afternoon and evening as pollen collected early in the day goes toward larval provisioning.
This is a list of crop plants pollinated by bees along with how much crop yield is improved by bee pollination. [1] Most of them are pollinated in whole or part by honey bees and by the crop's natural pollinators such as bumblebees, orchard bees, squash bees, and solitary bees. Where the same plants have non-bee pollinators such as birds or ...
Males can often be seen in large numbers flying around shrubs with large flowers, such as Rose of Sharon. Agapostemon angelicus is native to the Texas high plains. They specialized in being pollinators for cotton. [3] They can serve as a replacement for honey bees in pollination. [4]

Ptilothrix species are solitary, ground-nesting bees. These bees have especially prominent hairs in the scopae of their hind legs, to help gather pollen to provision their nests. Ptilothrix species specialize on certain families of plants for their pollen, including the families Malvaceae , Convolvulaceae , Onagraceae , Cactaceae ...
