The Rhathymini are a tribe of kleptoparasitic apid bees ("cuckoo bees"). [1] [2]
The Rhathymini consists of bees typically moderate to large in size, ranging 13–28 mm (0.51–1.10 in) body length. [3]
Visually, scholars have compared their appearance to that of vespid wasps (especially Polistes ), or the giant species of the bee genus Nomada. [3]
As a kleptoparasitic species, the Rhathymini forego the typical pollination process common amongst bee species to feed their offspring, and instead lay their eggs within the nests already provisioned by other bee species. [1]
Rhathymini have been documented to display aggression toward other bee ecosystems, including documented instances of attacking the nests of other bees. [1] [4]
Apidae is the largest family within the superfamily Apoidea, containing at least 5700 species of bees. The family includes some of the most commonly seen bees, including bumblebees and honey bees, but also includes stingless bees, carpenter bees, orchid bees, cuckoo bees, and a number of other less widely known groups. Many are valuable pollinators in natural habitats and for agricultural crops.
The term cuckoo bee is used for a variety of different bee lineages which have evolved the kleptoparasitic behaviour of laying their eggs in the nests of other bees, reminiscent of the behavior of cuckoo birds. The name is perhaps best applied to the apid subfamily Nomadinae, but is sometimes used in Europe to mean bumblebees (Bombus) in the subgenus Psithyrus. Females of cuckoo bees are easy to recognize in almost all cases, as they lack pollen-collecting structures and do not construct their own nests. They often have reduced body hair, abnormally thick and/or heavily sculptured exoskeleton, and saber-like mandibles, although this is not universally true; other less visible changes are also common.
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.
Nomadinae is a subfamily of bees in the family Apidae. They are known commonly as cuckoo bees.
With over 850 species, the genus Nomada is one of the largest genera in the family Apidae, and the largest genus of cuckoo bees. Cuckoo bees are so named because they enter the nests of a host and lay eggs there, stealing resources that the host has already collected. The name "Nomada" is derived from the Greek word nomas, meaning "roaming" or "wandering."
The genus Megachile is a cosmopolitan group of solitary bees, often called leafcutter bees or leafcutting bees; it also includes the called resin bees and mortar bees. While other genera within the family Megachilidae may chew leaves or petals into fragments to build their nests, certain species within Megachile neatly cut pieces of leaves or petals, hence their common name. This is one of the largest genera of bees, with more than 1500 species in over 50 subgenera. The alfalfa leafcutter bee is managed on a commercial scale for crop pollination, and has been introduced by humans to various regions around the world.
The sweat bee genus Lasioglossum is the largest of all bee genera, containing over 1800 species in numerous subgenera worldwide. They are highly variable in size, coloration, and sculpture; among the more unusual variants, some are cleptoparasites, some are nocturnal, and some are oligolectic. Most Lasioglossum species nest in the ground, but some nest in rotten logs.
Eulaema is a genus of large-bodied euglossine bees that occur primarily in the Neotropics. They are robust brown or black bees, hairy or velvety, and often striped with yellow or orange, typically resembling bumblebees. They lack metallic coloration as occurs in the related genus Eufriesea.
Exaerete is a genus of euglossine bees found from Mexico to northern Argentina. Like all orchid bees, they are restricted to the Neotropics. All but one species is metallic green, and they are cleptoparasites in the nests of other euglossines in the genera Eufriesea and Eulaema. It contains the following species:
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.
Exomalopsis is a genus of bees in the family Apidae. They occur in the Western Hemisphere.
Exaerete smaragdina is a species of kleptoparasitic euglossine bees.
Eufriesea surinamensis belongs to the tribe of euglossine bees and as such is a species of orchid bee. This should not be mistaken with the species group surinamensis, which includes Ef. surinamensis among other Eufriesea species.
Triepeolus is a genus of cuckoo bees in the family Apidae. There are at least 140 described species in Triepeolus. The majority of species whose life history is known are kleptoparasitic in the nests of bees in the tribe Eucerini, especially the genera Melissodes and Svastra.
Anthidiini is a tribe of insects in the family Megachilidae. There are at least 40 genera and 840 described species in Anthidiini. There is strong evidence that the tribe is monophyletic.
Augochlorella is a genus in the bee family Halictidae, commonly called sweat bees. They display metallic coloration, ranging from reddish to gold to bluish green, as is typical for other genera in the tribe Augochlorini.
Stelis is a genus of kleptoparasitic cuckoo bees in the family Megachilidae. There are at least 100 described species in Stelis.
Roubikia is a genus of bee-associated mites occurring in the neotropics. They are mutualists or commensals, and feed on fatty acids from floral oils and most likely on fungi. The type species is Chaetodactylus panamensis.
Austroplebeia is a stingless bee (Meliponini) genus in the family Apidae. The genus was erected by Jesus Santiago Moure in 1961. The genus comprises five described species endemic to Australia and New Guinea. Austroplebeia are more closely related to the African stingless bees than rest of the species found in Asia and Australia.
Meloetyphlus fuscatus, the blind blister beetle, is a species of blister beetle in the family Meloidae found in Central and South America. They are kleptoparasites of orchid bees and are entirely blind as adults. Unique among meloids, females do not lay their eggs near flowers, but rather within their hosts' nests.
