Pollinating Honey Bee Behavior of Large Black Beesīoth of these bees have extremely different behavior. Carpenter bees could be the problem if you're seeing big black bees near your home. In addition, carpenter bees can cause damage to your home if they nest in the wood. This avoids the transferring of pollen all together. These black bees are known for robbing pollen from plants by creating a hole near the base of the flower to easily access the nectar. On the other hand, carpenter bees are not strong pollinators. Currently, the pollinator population is declining, therefore, it is crucial we protect the species. Specifically, they are excellent buzz pollinators, which is the process of dislodging pollen from the flower by the vibrations of their flight muscles. Do Carpenter Bees Pollinate?īumble bees are important pollinators and are one of the few bee species who can pollinate. If you see large black bumble bees in your yard, there are some easy tell-tale signs for distinguishing between the two. Both are approximately the same size and can be found in some of the same places, including your garden. Provided per female.Carpenter bees and bumble bees are often confused for one another. ½” makes it easier to drill the holes without crossing tunnels, especially with longerĭrill bits which tend to bend during drilling. Neighboring holes can be quite close, but separating holes by about For blue orchard bees, a ¼” drill bit works well, drilling to a depth ofĤ to 7 inches. Providing blocks of lumber or natural logs drilled with holes will attract many nestingįemales of the blue orchard bee, and will attract other beneficial solitary bee speciesĪs well. The nests are built in natural cavities in wood, such as beetle tunnels, or in human-madeĬavities such as gaps in the siding on buildings. Blue orchard bee nests consist of a linear series of cellsĬontaining pollen and nectar masses (“bee bread”) for the larvae individual cellsĪre separated by plugs of dried mud collected by the female. Makes management convenient because large nest-hole arrays can be provided for them Likes to nest in aggregations containing the nests of many other females. However, like other species of solitary bee, the blue orchard bee Female solitary bees build and provision their nests For example, Osmia aglaia is a good pollinator for raspberries and other cane fruits in the Pacific Northwestīlue orchard bees are solitary bees, meaning that they do not live in colonies like Other Osmia species are also useful to commercial fruit production. Hundred blue orchard bees are required to pollinate one acre of apples or cherries. They can be managed intentionally by providing appropriate nesting materials,Īnd populations can be augmented by purchasing additional bees. The blue orchard bee is a common and widely distributed native bees,Īnd will often turn up opportunistically wherever their preferred pollen sources areĪvailable. Peaches, nectarines, and pears) either alone or as a supplement along with hives of The blue orchard bee, Osmia lignaria, is used to pollinate orchard fruits (cherries, apple, apricot, almond, plums/prunes,
