The species is unique as it is an oligolectic bee, foraging mainly for floral oils from Primulaceae of the genus Lysimachia. collects pollen and deposits it, in the form of a ball, in the bees (Genus Xylocopa Latreille) of the Western Hemisphere also vulnerable. As the only native bee, Xylocopa darwini serves as an important primary pollinator within the plant-pollinator network of the archipelago. After collecting pollen and preparing tunneled chambers out of wood, a single female will deposit eggs on pollen balls within the chamber and seal it.

The tunnels average 6 to 10 in (15 to 25 cm) in length and consist of a linear series of partitioned brood cells. Xylocopa varipunctaPatton, 1879Xylocopa aeneipennisPerkins, 1899. Infraclassis: Neoptera Carpenter bees have a wide range of mating strategies between different species. [8][17], X. sonorina in a field of Chinese violet (Asystasia gangetica), Some flowers protect themselves from robbery with adaptive structures such as strong plant walls or by producing extrafloral nectar which is visited by ants that inhibit the bees from robbing the nectar, though ant guards are only effective against certain bee species (not Xylocopa).
[7] This was confirmed in 2020 using DNA analysis, and as the name sonorina has seniority, this is the valid species name.[10]. This is what makes them a threat to homeowners in the region. In April, new adults emerge from their nest for mating season, but each generation only lives for a year.
capacity of these bees by others, possibly their sisters. to develop a nest as a single female, and later may be joined by In general, the biology and ecology of X. sonoria conforms The females, on the other hand, fit the more standard description of other carpenter bees. [8], In 1899, R. C. L. Perkins described the same species as Xylocopa aeneipennis, and in 1922, P. H. Timberlake claimed that the Hawaiian Xylocopa was the same as the mainland X. varipuncta, that had been named in 1879, [9] and Roy Snelling predicted in 2003 that X. varipuncta would eventually be reclassified as a synonym of X. sonorina. Subgenus: Xylocopa (Neoxylocopa) [24] These pheromones are long-range attractants and are used as male advertisements. These bees feed on pollen and nectar and display sexual dimorphism. [11] [12] The adult bees spend the winter in the tunnels. The southern carpenter bee can be found mainly in the coastal and gulf regions of the southeastern United States, as well as Mexico and Guatemala. If you would like to participate, please visit the project page, where you can join the discussion and see a list of open tasks. There is physiological transfer of large amounts of heat to the abdomen and to the head during pre-flight warming and thoracic heating. Gerling, D. 1983. This species, mainly found in the Hawaiian Islands, is said have arrived there through commerce between the islands and mainland United States going back as far as 1874. attack. [3] Females are black while males are golden-brown with green eyes.
[24] Three observations were made that helped form this conclusion: Non-resource-based territoriality evolved from food source territoriality as a response to a low density of bees. The name "carpenter" comes from the fact that these bees excavate nests inside a variety of woods, [18] and the species' common name refers to the Californian Central Valley in which they are commonly found. tunnel at a point furthest from the entrance. Because of our tropical climate, egg laying by female carpenter
Xylocopa pubescens is a species of large carpenter bee. Entomologist Julian R. Yates III of the University of Hawaii at Manoa describes the life cycle of X. sonorina in Hawaii: Having located a suitable piece of wood, the female bee begins to excavate a single tunnel in preparation for egg laying.
Finally, fluctuating or declining territory value should reduce the extent of site fidelity. Its only other habitat as of 2020 is on Kangaroo Island in South Australia. Megachile rotundata, the alfalfa leafcutting bee, is a European bee that has been introduced to various regions around the world. In tropical climates, females … Each cell a female provisions contains a substance called "bee bread", which is a mixture of pollen and nectar used as food for the larvae. [20] Another study found that X. sonorina was a primary and secondary nectar "robber" of A. gangetica since it "took nectar through perforations and did not contact stigmas in doing so." The male has bright yellow marks on the lower part of its face and some yellow hairs on the top front of its thorax. Because of this, sightings are rare and little is known about the species. Subordo: Apocrita Materials and Methods Observations were conducted of … [1] Males are golden brown and lack stingers; females are black and larger than the males and considered shy. One or more cooperating females build many brood cells. Identification . If abandoned galleries are reused, their length and All nesting cycles for all species of Xylocopa show common features. Sciences, University of California, Berkeley.
The main exceptions are species in the subgenus Proxylocopa; they dig nesting tunnels in suitable soil. This species constructs their nests in dead native softwoods such as coffee plants, cottonwood, Douglas fir, incense cedar, Mexican pine, coast redwood and giant redwood. It is not known when X. sonorina was introduced to the Hawaiian Islands, but it occurred prior to 1874, when British entomologist Frederick Smith originally named the species, and X. sonorina is currently found on all of the main Hawaiian Islands and in the Mariana Islands.

Xylocopa virginica is sympatric with Xylocopa micans in the southeastern United States. As a solitary bee species, it does not build colonies or store honey, but is a very efficient pollinator of alfalfa, carrots, other vegetables and some fruits. [11][12] The adult bees spend the winter in the tunnels. Smith's original description was: Female.—Black; head and thorax closely and moderately punctured; the mesothorax smooth, impunctate and shining on the disk; metathorax rounded behind; abdomen shining rather finely punctured, most closely so at the sides above; the pubescence entirely black, except that on the anterior tarsi beneath, which is ferruginous; the claws of the tarsi ferruginous; wings fusco-hyaline, with a darker cloud beyond the enclosed cells, and adorned with a bright purple and coppery iridescence. Unlike the mican species, the virginica species can be found in almost half of the United States and into Canada, favoring climates east of the Rocky Mountains.
Physiological heat transfer to head or abdomen would not be apparent from body temperatures due to the rapid convective cooling, especially at high air temperatures when flight speed increases; thermoregulation involves a strong reliance on forced convection as a result of changes in flight speed, with active heat transfer to the abdomen and evaporative heat loss from the head at high temperatures. Carpenter bees have largely naked abdomens, separating them from bumble bees. Males are golden brown and lack stingers; females are black and larger than the males and considered shy.
Aerosol stream (as opposed to spray) This species, mainly found in the Hawaiian Islands, is said have arrived there through commerce between the islands and mainland United States going back as far as 1874. Size .
They nest in various types of wood and eat pollen and nectar. Occasionally, they are also found in the mountains. Nishida, Toshiyuki (1963). Like most native bees, females are not aggressive, and will normally sting only when provoked,[12] while the males do not have stingers.
1982. In a 1996 study using Asystasia gangetica (Chinese violet), X. sonorina visited 16 flowers per minute and spent an average of 1.5 seconds at each flower, usually flying towards the flower from the front, landing on the petals, and moving to the bottom of the corolla. For many years, the sonoria were misidentified as varipuncta. Males mostly disperse and leave their home nests, while females have been observed to possess philopatric behavior. Xylocopa is a genus of large, robust bees, often confused with bumble-bees by the general public. Like most bees in its genus, the southern carpenter bee is considered a solitary bee because it does not live in colonies. especially those of the Papilionaceae. Superordo: Hymenopterida
With a short life cycle, these carpenter bees mate in the early spring and lay eggs around July. However, the californica species are a bit more metallic in appearance. The eggs hatch in two to three days.
