Bombus Vagans
The half-black bumblebee (''Bombus vagans'') is a small bumblebee with a wide distribution in North America, its range extending from Ontario to Nova Scotia and southward to Georgia. Description ''Bombus vagans'' is a common species of bumblebee with a medium-length tongue. The head, thorax and first two segments of the abdomen are yellow while the rest of the abdomen is black. The face has a mixture of yellow and black hairs and the thorax is densely clad in shaggy yellow hair except for a smooth central portion which is bare and shiny. The first two abdominal segments bear yellow hairs and the remainder of the abdomen is clad in black hairs. The underside of this bee and the legs are black. Similar species with which it can be confused include ''Bombus sandersoni'' (which is slightly smaller), ''Bombus perplexus'', ''Bombus impatiens'' and '' Bombus affinis''. Behavior This bee comes out from hibernation quite late in the year with the first queens being seen in early May in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Insects Described In 1854
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bumblebees
A bumblebee (or bumble bee, bumble-bee, or humble-bee) is any of over 250 species in the genus ''Bombus'', part of Apidae, one of the bee families. This genus is the only extant group in the tribe Bombini, though a few extinct related genera (e.g., ''Calyptapis'') are known from fossils. They are found primarily in higher altitudes or latitudes in the Northern Hemisphere, although they are also found in South America, where a few lowland tropical species have been identified. European bumblebees have also been introduced to New Zealand and Tasmania. Female bumblebees can sting repeatedly, but generally ignore humans and other animals. Most bumblebees are social insects that form colonies with a single queen. The colonies are smaller than those of honey bees, growing to as few as 50 individuals in a nest. Cuckoo bumblebees are brood parasitic and do not make nests or form colonies; their queens aggressively invade the nests of other bumblebee species, kill the resident queen ...

Apicystis Bombi
''Apicystis bombi'' is a species of parasitic alveolates in the phylum Apicomplexa. It infects bees, especially bumblebees. It is believed to have a cosmopolitan distribution in bumblebees and a sporadic occurrence in honey bees, and causes disease symptoms in nonresistant bee species. Taxonomy This protozoan was first described by Liu in 1974 as ''Mattesia bombi''. In 1996, Lipa and Triggiani transferred it to the new genus ''Apicystis'' on the basis of morphology and life cycle. Distribution This protozoan was found in Canada in overwintering queens and in males of various species of ''Bombus'', with the half-black bumblebee (''Bombus vagans'') at 8% being the most heavily infected species. It was later identified in ''Bombus'' species in France, and also in Switzerland, where infection rates varied between 4 and 7%. The oocysts were found in Italy in the garden bumblebee ('' B. hortorum'') and the buff-tailed bumblebee ('' B. terrestris'') and in 1990, in Finland, were found ...

Bombus Citrinus
''Bombus citrinus'' is a species of bumblebee known commonly as the lemon cuckoo bumblebee due to its lemon-yellow color. It is native to eastern North America.Hatfield, R., et al. 2014''Bombus citrinus''.The IUCN Red List of Threatened Species. Downloaded on 04 March 2016. This is a cuckoo bumblebee, one that invades the colonies of other bumblebees, kills the resident queen, and takes control over the population of workers inside. Host bees for this species include the common eastern bumblebee (''Bombus impatiens'') and the half-black bumblebee ('' B. vagans''). Before the queen invades a nest she forages on various plants, such as asters, thistles, snakeroots, blazing-stars, mountain-mints, and goldenrods. Phylogeny ''Bombus citrinus'' belongs to the parasitic ''Bombus'' subgenus ''Psithyrus''. A previous classification had ''Psithyrus'' listed as its own genus, and so this species used to be identified as ''Psithyrus citrinus''. Members of ''Psithyrus'' are distinguis ...

Psithyrus
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] |
Goldenrod
Goldenrod is a common name for many species of flowering plants in the sunflower family, Asteraceae, commonly in reference to the genus ''Solidago''. Several genera, such as ''Euthamia'', were formerly included in a broader concept of the genus ''Solidago''. Some authors treat ''Oligoneuron'', the flat-topped goldenrods, as a separate genus than ''Solidago'', while others consider it a section: ''Solidago'' sect. ''Ptarmicoidei''. Goldenrods can be used as a sustainable method to enrich soil with nitrogen. With an increase of nitrogen levels, there can then be an increase of vegetative growth. Plants known as goldenrods include: *''Bigelowia'' spp., rayless goldenrods, 2 species native to the Southeastern United States *''Cuniculotinus gramineus'', Panamint rock goldenrod *''Euthamia'' spp., flat-topped goldenrods or grass-leaved goldenrods, 5 species native to North America *''Gundlachia triantha'', Trans-Pecos desert goldenrod *'' Lorandersonia microcephala'', small-headed ...

Aster (genus)
''Aster'' is a genus of perennial flowering plants in the family Asteraceae. Its circumscription has been narrowed, and it now encompasses around 170 species, all but one of which are restricted to Eurasia; many species formerly in ''Aster'' are now in other genera of the tribe Astereae. ''Aster amellus'' is the type species of the genus and the family Asteraceae. The name ''Aster'' comes from the Ancient Greek word (''astḗr''), meaning "star", referring to the shape of the flower head. Many species and a variety of hybrids and varieties are popular as garden plants because of their attractive and colourful flowers. 'Aster' species are used as food plants by the larvae of a number of Lepidoptera species—see list of Lepidoptera that feed on ''Aster''. Asters can grow in all hardiness zones. Circumscription The genus ''Aster'' once contained nearly 600 species in Eurasia and North America, but after morphologic and molecular research on the genus during the 1990s, it was ...

Eupatorium
''Eupatorium'' is a genus of flowering plants in the family Asteraceae, containing from 36 to 60 species depending on the classification system. Most are herbaceous perennials growing to tall. A few are shrubs. The genus is native to temperate regions of the Northern Hemisphere. Most are commonly called bonesets, thoroughworts or snakeroots in North America. The genus is named for Mithridates Eupator, king of Pontus. Systematics and taxonomy ''Eupatorium'' has at times been held to contain as many as 800 species, but many of these have been moved (at least by some authors) to other genera, including ''Ageratina'', ''Chromolaena'', '' Condylidium'', '' Conoclinium'', '' Critonia'', ''Cronquistianthus'', ''Eutrochium'', '' Fleischmannia'', '' Flyriella'', '' Hebeclinium'', '' Koanophyllon'', ''Mikania'', and '' Tamaulipa''. The classification of the tribe Eupatorieae, including species placed in ''Eupatorium'' in the present or past, is an area of ongoing research, so further ch ...

Bombus Perplexus
''Bombus perplexus'' is a species of bumblebee known by the common name confusing bumblebee.Hatfield, R., et al. 2014''Bombus perplexus''.The IUCN Red List of Threatened Species. Downloaded on 09 March 2016.NatureServe. 2015''Bombus perplexus''.NatureServe Explorer Version 7.1. Accessed 9 March 2016. It is native to northern North America, where it occurs across Canada and into the eastern United States. The queen is 1.7 to 2.1 centimeters long and just under a centimeter wide at the abdomen. It is mostly black with areas of pale hairs. The worker female is 1.2 to 1.4 centimeters long and half a centimeter wide. It is hairier than the queen and has more yellow hairs. The abdomen is black and yellow. The male is the same size as the worker. The mandibles have reddish tips. It has white hairs on the head and legs and yellow and white hairs on the thorax.

Cirsium
''Cirsium'' is a genus of perennial and biennial flowering plants in the Asteraceae, one of several genera known commonly as thistles. They are more precisely known as plume thistles. These differ from other thistle genera ('' Carduus'', ''Silybum'' and ''Onopordum'') in having feathered hairs to their achenes. The other genera have a pappus of simple unbranched hairs. They are mostly native to Eurasia and northern Africa, with about 60 species from North America (although several species have been introduced outside their native ranges). Thistles are known for their effusive flower heads, usually purple, rose or pink, also yellow or white. The radially symmetrical disc flowers are at the end of the branches and are visited by many kinds of insects, featuring a generalised pollination syndrome. They have erect stems and prickly leaves, with a characteristic enlarged base of the flower which is commonly spiny. The leaves are alternate, and some species can be slightly hairy. E ...
