Pollinator decline is the reduction in abundance of insect and other animal pollinators in many ecosystems worldwide that began being recorded at the end of the 20th century. Multiple lines of evidence exist for the reduction of wild pollinator populations at the regional level, especially within Europe and North America.
The decline was "apparent regardless of habitat type" and could not be explained by "changes in weather, land use, and habitat characteristics". The authors suggested that not only butterflies, moths and wild bees appear to be in decline, as previous studies indicated, but "the flying insect community as a whole". [1] [4] [52] [53] [54]

Starting in 2006, California almond growers began to suffer losses due to colony collapse disorder, a poorly understood phenomenon resulting in the decline of bee populations. [2] While this increased pollination expenses for many growers, high demand for almonds created an incentive to transport bees from across the United States to California.
They have been found from the Mediterranean California all the way up to the Tundra regions of Alaska, making them one of the bees with the widest range geographic range. [4] However, recently there has been a noticeable decline in population. [5] In the past decade, the population of B. occidentalis has dropped by around 40.32%.

Honey bee starvation is a problem for bees and beekeepers.Starvation may be caused by unfavorable weather, disease, long distance transportation or depleting food reserve. Over-harvesting of honey (and the lack of supplemental feeding) is the foremost cause for scarcity as bees are not left with enough of a honey store, though weather, disease, and disturbance can also cause problem
