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, which dig nesting tunnels in suitable soil.
In paleontology, a Lazarus taxon is a taxon that disappears for one or more periods from the fossil record, only to appear again later. Likewise in conservation biology and ecology, it can refer to species or populations that were thought to be extinct, and are rediscovered. The term Lazarus taxon was coined by Karl W. Flessa and David Jablonski in 1983 and was then expanded by Jablonski in 1986. Paul Wignall and Michael Benton defined Lazarus taxa as, "At times of biotic crisis many taxa go extinct, but others only temporarily disappeared from the fossil record, often for intervals measured in millions of years, before reappearing unchanged". Earlier work also supports the concept though without using the name Lazarus taxon, like work by Christopher R. C. Paul.
Megachile pluto, also known as Wallace's giant bee or raja ofu, is a large resin bee found in Indonesia. With a wingspan of 63.5 mm (2.5 in) it is the largest known living bee species. It was believed to be extinct until several specimens were discovered in 1981. No further sightings were confirmed until two specimens were collected and sold on eBay in 2018. A live female was found and filmed for the first time in 2019.
Hylaeus is a large and diverse cosmopolitan genus within the bee family Colletidae. This genus is also known as the yellow-faced bees or masked bees. This genus is the only truly globally distributed colletid, occurring on all continents except Antarctica.
Hylaeus alcyoneus, commonly known as the banksia bee, is a bee species endemic to Australia where it is commonly found in the coastal heaths of eastern and southern Western Australia. This bee is an important pollinator of Banksia species.
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.
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.
Hylaeus sanguinipictus is a bee species endemic to Western Australia. It was described in 1914 from material collected in Yallingup by Theodore Dru Alison Cockerell as Prosopis sanguinipicta.
Hylaeus agilis is a bee species in the family Colletidae. It is endemic to New Zealand. This species is found throughout the country and visits the flowers of a wide variety of plant species, both native and introduced.
Hylaeus modestus, also known as the modest masked bee, is a species of hymenopteran in the family Colletidae. It is found in North America.
Homalictus is a subgenus of bees in the genus Lasioglossum subfamily Halictinae of the family Halictidae. They are found in Sri Lanka, Southeast Asia, east across the Pacific to the Mariana Islands, Samoa, Fiji and are most prevalent in Australia.
Leioproctus boltoni is a species of bee in the family of plasterer bees. This species was first described in 1904 and is endemic to New Zealand. They are a solitary bee, small and black in appearance. L. boltoni can be found throughout the main islands of New Zealand and forages on the flowers of both native and introduced species of plants. This species nests in the soil with their life cycle lasting approximately a year.
Megalopta is a widespread neotropical genus of bees in the tribe Augochlorini in family Halictidae, known as the sweat bees. They are the largest of the five nocturnal genera in Augochlorini. Most have pale integumentary pigmentation, and all have large ocelli, most likely a feature of their nocturnal behavior. They live in tropical Central America and the entirety of South America. The subgenus Noctoraptor is cleptoparasitic. They are not known from the fossil record.
Bombus irisanensis is a rare species of bumblebee endemic to Luzon in the Philippines.
Hylaeus relegatus is a bee species in the family Colletidae. It is endemic to New Zealand and was first described by Frederick Smith. It is the largest and most common species of this genus in that country. H. relegatus can be found throughout the three main islands of New Zealand and visits the flowers of a wide variety of plant species, both native and introduced. Although widespread, this species is not abundant at any one particular location. It has been hypothesised that human made nest sites can be used to increase its numbers.
Hylaeus euxanthus is a species of hymenopteran in the family Colletidae and the subgenus Gnathoprosopis. It is found in Australia.
Austroplebeia cassiae is a small eusocial stingless bee first described by Cockerell in 1910 and it is found in Australia.
Austroplebeia essingtoni is a small eusocial stingless bee first described by Cockerell in 1905 and it is found in Australia. They are one of the smallest stingless bees in Australia and can survive in very arid areas with annual rainfalls down to 300 mm.
Hylaeus foveatus, a wasp-like bee, is a species of hymenopteran in the family Colletidae and the subfamily Analastoroides. It is found in Victoria and New South Wales in Australia.
Hylaeus nigritus, also known as the black masked bee, is a species of solitary bee native to much of Europe, with sightings and preserved specimens recorded as far east as Nizhny Novgorod, Russia and the Caucuses.
