What the difference between Specialist Bees and Generalist Bees?

---

Most Bees can be separated into 2 categories of female pollen preferences, either specialists or generalists. Specialist bees have evolved a specific relationship with a few or even just one plant species. Some specialist bees forage for pollen that can only be found on one plant species. These specialist bees emerge from their nests at te same time their host plant begins to flower. The host flower sometimes depends on pollination from one specific bee species and the bee depends on pollen from their specific flower species. This mutualistic relationship can be found all over the world.

Generalist bees are not too picky about the flowers they visit, and often visit a wide range of flower types and species when seeking out pollen.
