Psithyrus Citrinus
Cuckoo bumblebees are members of the subgenus ''Psithyrus'' in the bumblebee genus ''Bombus''. Until recently, the 28 species of ''Psithyrus'' were considered to constitute a separate genus. They are a specialized socially parasitic lineage which parasitises the nests of 'true' bumblebees, resulting in the loss of the ability to collect pollen and establish their own nests. Cuckoo bumblebees do not create a worker caste and produce only male and female reproductives. They are considered inquilines in the colonies of 'true' bumblebees. Cuckoo bumblebee females emerge from hibernation later than their host species to ensure that their host has had sufficient time to establish a nest. Before finding and invading a host colony, a ''Psithyrus'' female feeds directly from flowers until her ovaries are sufficiently developed, at which time she begins seeking a nest to invade. Once she has located and infiltrated a host colony, the ''Psithyrus'' female usurps the nest by killing or su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bombus Bohemicus
''Bombus bohemicus'', also known as the gypsy's cuckoo bumblebee, is a species of socially parasitic cuckoo bumblebee found in most of Europe with the exception of the southern Iberian Peninsula and Iceland. ''B. bohemicus'' practices inquilinism, or brood parasitism, of other bumblebee species. ''B. bohemicus'' is a generalist parasite, successfully invading several species from genus ''Bombus''. The invading queen mimics the host nest's chemical signals, allowing her to assume a reproductively dominant role as well as manipulation of host worker fertility and behavior. Taxonomy and phylogeny ''B. bohemicus'' is part of the order Hymenoptera, which includes ants, bees, wasps, and sawflies, the family ''Apidae'', specific to bees, and the genus ''Bombus'', which includes all bumblebees. ''B. bohemicus'' belongs to the subgenus ''Psithyrus'', or the cuckoo bees, which includes 29 species found in Europe and the New World. Species in this subgenus are obligate parasites of other ...

Charles D
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed its de ...

Bombus Vestalis
''Bombus vestalis'', the vestal cuckoo bumblebee, is a species of cuckoo bumblebee that lives in most of Europe, as well as North Africa and western Asia. It is a brood parasite that takes over the nests of other bee species. Its primary host is ''Bombus terrestris'' (the buff-tailed bumblebee). After its initial classification as ''Psithyrus vestalis'', this bumblebee recently was reclassified into the genus ''Bombus'', subgenus ''Psithyrus''. Description The queen is a large bumblebee with a length up to and a wingspan of ; the male is considerably smaller (). The bumblebee is predominantly black, with an orange collar. The third tergite has a border of yellow hairs, and the hairs on the fifth tergite are mostly white. The males are similar to the females, but smaller and with longer antennae. It is similar in appearance to another cuckoo bumblebee, ''Bombus bohemicus'', but is distinguishable by either the length of the antennal segments or dissection and comparison of the ...

Bombus Variabilis
''Bombus variabilis'' is a critically endangered species of cuckoo bumblebee Cuckoo bumblebees are members of the subgenus ''Psithyrus'' in the bumblebee genus ''Bumblebee, Bombus''. Until recently, the 28 species of ''Psithyrus'' were considered to constitute a separate genus. They are a specialized Social parasitism (b .... ''B. variabilis'' is a parasitic species. Females kill and replace the queens of '' B. pensylvanicus'', taking over their nests in the process. The decline of the latter as hosts can partially be linked to the decline of ''B. variabilis''. This species of bee can be distinguished by the lack of pollen baskets. The bee features have a dark face with yellow hair in its vertex and with dark brown wings. Its thorax has variations between black spots or patches. For females, they only have black abdomens but males can vary in their hair color patterns.''

Bombus Sylvestris
''Bombus sylvestris'', known as the forest cuckoo bumblebee or four-coloured cuckoo bee, is a species of cuckoo bumblebee, found in most of Europe and Russia. Its main hosts are '' Bombus pratorum'', '' Bombus jonellus'', and '' Bombus monticola''. As a cuckoo bumblebee, ''Bombus sylvestris'' lays its eggs in another bumblebee's nest. This type of bee leaves their young to the workers of another nest for rearing, allowing cuckoo bumblebees to invest minimal energy and resources in their young while still keeping the survival of their young intact. Taxonomy and phylogeny ''Bombus sylvestris'' belongs to the order Hymenoptera. Specifically, the species falls under the family Apidae, which further subdivides into the subfamily Apinae, and then the tribe Bombini. Description and identification This is a small bumblebee; the queen has a body length of and the male one of . The head is round, and the proboscis is short. Its fur is black with a yellow collar and a white tail. So ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bombus Suckleyi
''Bombus suckleyi'' is a species of bumblebee known commonly as Suckley's cuckoo bumblebee, named after biologist George Suckley.NatureServe. 2015''Bombus suckleyi''.NatureServe Explorer Version 7.1. Accessed 10 March 2016. Suckley's bumble bee is a generalist pollinator and represents a rare group of obligate, parasitic bumble bees (cuckoo bumble bees). Suckley's bumble bee is a social-parasite because it invades the nests of the host bumble bees, including the western bumble bee (''Bombus occidentalis''), and relies on host species workers to provision its larvae. It is native to northwestern North America, including Alaska and parts of western and central Canada and the western United States. Taxonomy Bumble bees are members of the genus ''Bombus'' within the insect order Hymenoptera and family Apidae. ''Bombus suckleyi'' was first described by John Greene and named after George Suckley. Suckley's bumble bee and all cuckoo bumble bees are classified under the subgenus ''Psithy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
