Xylocopa sonorina, the valley carpenter bee or Hawaiian carpenter bee, [2] is a species of carpenter bee found from western Texas to northern California, [3] and the eastern Pacific islands. [4] Females are black while males are golden-brown with green eyes.
Firstly, nectar robbers, such as carpenter bees, bumble bees and some birds, can pollinate flowers. [1] Pollination may take place when the body of the robber contacts the reproductive parts of the plant while it robs, or during pollen collection which some bees practice in concert with nectar robbing.
In some plants, this reduces fruit and seed production, while others have developed defence mechanisms against nectar robbing. When foraging for pollen from some species with tubular flowers however, the same species of carpenter bees still achieve pollination, if the anthers and stigmata are exposed together. [7]
Many of the more than 400 species of native bees are also threatened, such as the rusty patch bumble bee. Susan Carpenter, the native plant garden curator at UW-Madison's arboretum, said she also ...
The blue carpenter bees fly from mid-March to mid-October, [5] collecting pollen at various families of plants, especially knapweed , yellow composites and Lotus . [ 6 ] Females dig the nest extracting the soft tissue that fills the cavities of the vertical or slanted dry plant stems and small branches, [ 7 ] [ 6 ] such as thistles ...
X. californica performs floral sonication to obtain pollen. [13] They do this by gripping the poricidal anthers with their mandibles and contracting their flight muscles, rapidly vibrating their body and the flower's anthers, releasing the pollen onto the abdomen and legs of the bees. [12] This process allows for pollination to happen.
Bees collecting pollen from sunflowers treated with Gaucho exhibited confused and nervous behavior; thus, the phenomenon was initially termed the "mad bee disease" — the bees, according to ...
X. virginica survive mostly on nectar and pollen. Newly emerged bees do not have food stored in their nest, but they are occasionally brought nectar. [2] X. virginica use their maxillae to penetrate the corolla of plants and reach the nectar stores, a behavior known as nectar robbing.
