Honeybees and Wild Native Bees are the main pollinators of fruits and vegetables in the United States, accounting for 75%.
Most people think of bees forming large hives or colonies. While the European honey bee forms large social colonies, making it well suited for transport, most native bees are solitary or form relatively small colonies. There is relitively little know about many native bee species.
Recently, honeybee populations have been falling around the world. Mass colony calapse has had a significant impact in both european bee populations and native bee populations.
Any garden can be mademore inviting for bees. Do not spray insecticides when pollinators are active, even "organically approved" insecticides can be toxic to bees. Plant local flora for your little friends to feed on, and chose landscaping that fit your environment. You can also fill a shallow plant saucer with pepples and water for beed to land on and drink from. Empty it every few days to prevent mosquitos.
