Bombus Balteatus
''Bombus balteatus'', the golden-belted bumble bee, is a species of bumblebee with a boreal and high altitude distribution in northern Eurasia and North America. Range and distribution This species is found in Finland, northern Sweden, Russia, and North America from arctic Alaska, Canada, and mountain ranges in the United States such as the Sierra Nevada and the White Mountains down south to New Mexico. Their preferred habitat includes high altitude and boreal regions, and they are often found at higher elevations than the tree line. ''Bombus balteatus'' is often most abundant where ''Castilleja'', '' Chrysothammnus'', and ''Mertensia'' plant species are common. Some populations of bees, including in the Rocky Mountains, specifically Mount Evans, Niwot Ridge and Pennsylvania Mountain have declined in the 21st century. Morphology ''Bombus balteatus'' is a long-tongued bumblebee. Often the tongue length reaches two-thirds or more the length of the body. This morphological ...

Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Sinc ...

Hymenoptera Of Europe
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindwings are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insects Described In 1832
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 (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes and one pair of antenna (biology), 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 taxon, 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 Natural environment, environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, ...

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 ...

Niche Construction
Niche construction is the process by which an organism alters its own (or another species') local environment. These alterations can be a physical change to the organism’s environment or encompass when an organism actively moves from one habitat to another to experience a different environment. Examples of niche construction include the building of nests and burrows by animals, and the creation of shade, influencing of wind speed, and alternation of nutrient cycling by plants. Although these alterations are often beneficial to the constructor, they are not always (for example, when organisms dump detritus, they can degrade their own environments). Evolution For niche construction to affect evolution it must satisfy three criteria: 1) the organism must significantly modify environmental conditions, 2) these modifications must influence one or more selection pressures on a recipient organism, and 3) there must be an evolutionary response in at least one recipient population caused ...

Rocky Mountains
The Rocky Mountains, also known as the Rockies, are a major mountain range and the largest mountain system in North America. The Rocky Mountains stretch in straight-line distance from the northernmost part of western Canada, to New Mexico in the southwestern United States. Depending on differing definitions between Canada and the U.S., its northern terminus is located either in northern British Columbia's Terminal Range south of the Liard River and east of the Trench, or in the northeastern foothills of the Brooks Range/ British Mountains that face the Beaufort Sea coasts between the Canning River and the Firth River across the Alaska-Yukon border. Its southernmost point is near the Albuquerque area adjacent to the Rio Grande rift and north of the Sandia–Manzano Mountain Range. Being the easternmost portion of the North American Cordillera, the Rockies are distinct from the tectonically younger Cascade Range and Sierra Nevada, which both lie farther to its west. The ...

Bombus Frigidus
''Bombus frigidus'', the frigid bumblebee, is a rare species of bumblebee largely found in Canada and parts of the United States. These bees have adapted to their cold environment by being able to keep their internal temperature within a certain range while also being able to expel heat to keep the colony warm. An additional adaptation to the cold is their reduced length of copulation. Also, ''B. frigidus'' has developed a relationship with '' Mertensia paniculata'' so that the flowers' color signals to the bees when to obtain nectar. Taxonomy and phylogeny ''Bombus frigidus'' was described in 1854 by Frederick Smith in the ''Catalogue of hymenopterous insects in the collection of the British Museum''. Some species from the Appalachians have been included with this species in the past, but not in newer sources. This bee can be confused with ''Bombus mixtus'' and '' Bombus balteatus''. Bees in the family Apidae consist of honey bees, bumblebees, and stingless bees. Descripti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bombus Hyperboreus
''Bombus hyperboreus'' is a species of Arctic bumblebee with a circumpolar distribution. The species is primarily found in the arctic areas of Greenland, northern Scandinavia, and Russia. In 2015 the nearctic species, '' Bombus natvigi'', was separated from this species, based on genetic analysis. Accordingly, ''Bombus hyperboreus'' is limited to the Palaearctic, despite older literature listing this species as occurring in the Nearctic. It is a brood parasite, and attacks and enslaves other bumblebee colonies in order to reproduce as they do not even have the ability to produce workers themselves. Most of its targets are colonies of species of the same subgenus, '' Alpinobombus''. Taxonomy and phylogeny ''Bombus hyperboreus'' was originally named ''B. arcticus'' in 1802. Zoologist Carl Schönherr independently named the species as ''B. hyperboreus'' in 1809. It was not until 1950 that ''B. hyperboreus'' was used commonly to identify the species, when it was recognized that the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
