Xylocopa caffra is a species of Afrotropical carpenter bee that ranges from west to central and southern Africa, besides Madagascar and some Indian Ocean archipelagos. [2]
The females are black with two white or yellow bands over the hind thorax and first abdominal segment respectively, while the males are uniform greenish yellow in colour. [3] Females with white bands are associated with dry climatic conditions during larval development, but females of either colour, or colour grade, may emerge from the same brood. [4] In the Western Cape all have yellow bands however. A form with orange-red bands occurs in East Africa. [5]
The species is at home in various habitat types, from moist coastal settings to dry savannah. The territorial males patrol small areas around particular plants or flowers. The females are solitary nesters in Aloe or Agave stems, tree branches or timber. [3] The nests are partitioned into various cells, separated by walls of glued wood residue. [2] A wide variety of plants are used as sources of nectar and pollen. [2]
As with other carpenter bees, the larvae are fed a mixture of pollen and nectar. The females have a mutualistic association with phoretic mites that are transported from nest to nest in an abdominal chamber, called the acarinarium. [2] [3] The mites feed on nest fungi that may otherwise infest the nectar and pollen provisions of the larvae. [2]
They are parasitized by various biota including Anthrax , Coelopencyrtus , Dinogamasus , Hyperechia , Physocephala , Sennertia and Synhoria . [2]
It has been recorded from Angola, Botswana, Cameroon, Central African Republic, Republic of the Congo, the Democratic Republic of the Congo, Ethiopia, Guinea, Kenya, Malawi, Mozambique, Somalia, South Africa, Namibia, Tanzania, Uganda, Zambia and Zimbabwe. In the Indian Ocean region it occurs in Madagascar, the Comoro Islands and Seychelles. [2]
It has two subspecies: [1]
Carpenter bees are species in the genus Xylocopa of the subfamily Xylocopinae. The genus includes some 500 bees in 31 subgenera. The common name "carpenter bee" derives from their nesting behavior; nearly all species burrow into hard plant material such as dead wood or bamboo. The main exceptions are species in the subgenus Proxylocopa; they dig nesting tunnels in suitable soil.
The subfamily Xylocopinae occurs worldwide, and includes the large carpenter bees, the small carpenter bees, the allodapine bees, and the relictual genus Manuelia.
Xylocopa virginica, more commonly known as the eastern carpenter bee, extends through the eastern United States and into Canada. They nest in various types of wood and eat pollen and nectar. The eastern carpenter bee is similar to most other bee species in that it does not have a queen; in Xylocopa virginica, females are responsible for reproduction, foraging, and nest construction, though they may sometimes have help from their daughters. Xylocopa virginica is sympatric with Xylocopa micans in the southeastern United States.
Xylocopa violacea, the violet carpenter bee, is the common European species of carpenter bee, and one of the largest bees in Europe. It is also native to Asia.
Bombus lucorum, the white-tailed bumblebee, is a species of bumblebee, widespread and common throughout Europe. This name has been widely used for a range of nearly identical-looking or cryptic species of bumblebees. In 1983, Scholl and Obrecht even coined the term Bombus lucorum complex to explain the three taxa that cannot be easily differentiated from one another by their appearances. A recent review of all of these species worldwide has helped to clarify its distribution in Europe and northern Asia, almost to the Pacific. B. lucorum reaches the Barents Sea in the North. However, in southern Europe, although found in Greece it is an upland species with its distribution never quite reaching the Mediterranean.
Xylocopa sonorina, the valley carpenter bee or Hawaiian carpenter bee, is a species of carpenter bee found from western Texas to northern California, and the eastern Pacific islands. Females are black while males are golden-brown with green eyes.
The two-spotted bumble bee is a species of social bumble bee found in the eastern half of the United States and the adjacent south-eastern part of Canada. In older literature this bee is often referred to as Bremus bimaculatus, Bremus being a synonym for Bombus. The bee's common name comes from the two yellow spots on its abdomen. Unlike many of the other species of bee in the genus Bombus,B. bimaculatus is not on the decline, but instead is very stable. They are abundant pollinators that forage at a variety of plants.
Bombus occidentalis, the western bumblebee, is one of around 30 bumblebee species present in the western United States and western Canada. A recent review of all of its close relatives worldwide appears to have confirmed its status as a separate species.
Xylocopa bombylans, the peacock carpenter bee, is a species of carpenter bee found in Australia. It gets its common name by its habit of burrowing into wood.
Parasitellus is a genus of mites in the family Parasitidae which are obligatory parasites of bumblebees. These mites can be found clinging to the carapace, sometimes in large numbers. Mites in this genus hibernate in the deutonymphal stage. In the tritonymph stage they can actively transfer from bumblebee to bumblebee from flowers, where they can survive up to 24 hours. After they arrive in a bumblebee nest, they will moult into adults. Whilst it is not known what factors trigger the mite to molt, in laboratory conditions P. fucorum were found to moult after eating fresh pollen, although overall moulting success was low. They are kleptoparasitic or neutral to beneficial, depending on life stage; females and deutonymphs feed on provisioned pollen, while other stages are predators of small arthropods.
Colletes hederae, the ivy bee, is a species of plasterer bee belonging to the family Colletidae subfamily Colletinae.
Anthidium maculosum is a species of bee in the family Megachilidae, the leaf-cutter, carder, or mason bees. It is a solitary bee where the males are territorial and the females take part in polyandry. The males of A. maculosum differ from most other males of bee species because the males are significantly larger than females. In addition, subordinate males that act as satellites are smaller than territory-owning males. This species can be found predominately in Mexico and the United States.
Ceratina cyanea, common name blue carpenter bee, is a species of bee belonging to the family Apidae, subfamily Xylocopinae.
Sphecodopsis is a genus of cleptoparasitic "cuckoo" bees in the family Apidae. Endemic to southern Africa, the wasp-like bees of this genus are generally small, varying from 3.9 to 9 mm in length, and mostly black, with orange-ish or reddish colouring of the metasoma in some of the species. The bee genus Scrapter is recognised as a host for the cleptoparasitic life cycle of some Sphecodopsis, but further data regarding preferred hosts is not available for most of the species.
Dufour's gland is an abdominal gland of certain insects, part of the anatomy of the ovipositor or sting apparatus in female members of Apocrita. The diversification of Hymenoptera took place in the Cretaceous and the gland may have developed at about this time as it is present in all three groups of Apocrita, the wasps, bees and ants.
The Oriental carpenter bee, Xylocopa nasalis, or Xylocopa (Biluna) nasalis, is a species of carpenter bee. It is widely distributed in Southeast Asian countries. It is a major pollinator within its ecosystem, and is often mistaken for a bumblebee. The species leads a solitary lifestyle with a highly female-biased colony in the nest.
Euglossa cordata is a primitively eusocial orchid bee of the American tropics. The species is known for its green body color and ability to fly distances of over 50 km. Males mostly disperse and leave their home nests, while females have been observed to possess philopatric behavior. Because of this, sightings are rare and little is known about the species. However, it has been observed that adults who pollinate certain species of orchids will become intoxicated during the pollination.
Xylocopa sulcatipes is a large Arabian carpenter bee. These multivoltine bees are known to take part in social nesting and cooperative nesting. These metasocial carpenter bees nest in thin dead branches. One or more cooperating females build many brood cells. They have been extensively studied in Saudi Arabia and Israel.
Xylocopa pubescens is a species of large carpenter bee. Females form nests by excavation with their mandibles, often in dead or soft wood. X. pubescens is commonly found in areas extending from India to Northeast and West Africa. It must reside in these warm climates because it requires a minimum ambient temperature of 18 degrees Celsius in order to forage.
Xylocopa micans, also known as the southern carpenter bee, is a species of bee within Xylocopa, the genus of carpenter bees. 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. Like all Xylocopa bees, X. micans bees excavate nests in woody plant material. However, unlike its sympatric species Xylocopa virginica, X. micans has not been found to construct nest galleries in structural timbers of building, making it less of an economic nuisance to humans. Carpenter bees have a wide range of mating strategies between different species. The southern carpenter bee exhibits a polymorphic mating strategy, with its preferred method of mating changing as the season progresses from early spring to mid summer. Like most bees in its genus, the southern carpenter bee is considered a solitary bee because it does not live in colonies.
