Andrena Astragali
''Andrena astragali'', the death camas miner bee or death camas bee, is a species of miner bee in the family Andrenidae. It is found in North America. It specializes in feeding on the highly poisonous ''Toxicoscordion venenosum'', the meadow deathcamas, and close relatives. It is quite likely the only bee that can tolerate the deathcamas toxin, zygacine. Taxonomy and phylogeny ''A. astragali'' is a bee, a species in the order Hymenoptera, which includes wasps, bees, and ants. It is in the family Andrenidae, and the subfamily Andreninae. Its genus, ''Andrena'', is one of the largest genus of bees and its members are solitary ground dwelling mining bees. The species was first described by two entomologists with the University of Colorado Boulder, Henry Lorenz Viereck and Theodore D. A. Cockerell, who published the first description of the species in 1914. It was inadvertently named a second time as ''Andrena zygadeni'' by Cockerell from specimens collected in California fe ...

Labrum (arthropod Mouthpart)
The labrum is a flap-like structure that lies immediately in front of the mouth in almost all extant Euarthropoda. The most conspicuous exceptions are the Pycnogonida, which probably are chelicerate-relatives. In entomology, the labrum amounts to the "upper lip" of an insect mouth, the corresponding "lower lip" being the labium. The evolutionary origin, embryogenesis and morphological development of the labrum have proved to be by far the most controversial and challenging topic in the study of arthropod head structures. Embryonic nature and origin of the labrum The labrum is innervated in crustaceans and insects from the tritocerebrum (the back of the brain). However, in development, its embryonic primordium often appears at the anterior of the head and migrates backwards towards its adult position. Furthermore, it often appears as a bilobed structure, with a set of muscles, nerves and gene expression in many ways similar to that of an appendage. This evidence has been use ...

Hymenoptera Of North America
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 co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meadow Death Camas
''Toxicoscordion venenosum'', with the common names death camas and meadow death camas, is a species of flowering plants in the genus '' Toxicoscordion'', of the Melanthiaceae family. It is native to western North America from New Mexico to Saskatchewan and west to the Pacific Ocean. The plant is called alapíšaš in Sahaptin, and nupqasaquⱡ ("nup-ka-sa-qush") in Ktunaxa. Description ''Toxicoscordion venenosum'' grows up to 70 cm tall with long, basal, grass-like leaves. The bulbs are oval and look like onions but do not smell like edible onions of the genus '' Allium''. The flowers are cream coloured or white and grow in pointed clusters, flowering between April and July. The flower clusters are a raceme (each cluster branches once along the main stalk), unlike its close relative '' Toxicoscordion paniculatum'', in which the flowers are born in a panicle (doubly branched flower stalks). The flowers have three sepals and three petals. Varieties Varieties include: * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honeybee
A honey bee (also spelled honeybee) is a eusocial flying insect within the genus ''Apis'' of the bee clade, all native to Afro-Eurasia. After bees spread naturally throughout Africa and Eurasia, humans became responsible for the current cosmopolitan distribution of honey bees, introducing multiple subspecies into South America (early 16th century), North America (early 17th century), and Australia (early 19th century). Honey bees are known for their construction of perennial colonial nests from wax, the large size of their colonies, and surplus production and storage of honey, distinguishing their hives as a prized foraging target of many animals, including honey badgers, bears and human hunter-gatherers. Only eight surviving species of honey bee are recognized, with a total of 43 subspecies, though historically 7 to 11 species are recognized. Honey bees represent only a small fraction of the roughly 20,000 known species of bees. The best known honey bee is the western honey ...

Osmia Lignaria
''Osmia lignaria'', commonly known as the orchard mason bee or blue orchard bee, is a megachilid bee that makes nests in reeds and natural holes, creating individual cells for its brood that are separated by mud dividers. Unlike carpenter bees, it cannot drill holes in wood. ''O. lignaria'' is a common species used for early spring fruit bloom in Canada and the United States, though a number of other ''Osmia'' species are cultured for use in pollination. Native origin ''O. lignaria'' is among 4000 native bee species of North America, and its species is divided by the Rocky Mountains into two subspecies, ''O. l. propinqua'' (western subspecies) and ''O. l. lignaria'' (eastern subspecies). The majority of research has been conducted in western orchards on the western subspecies. Efforts at establishing them outside their native range have met with mixed results. Researchers in one eastern study (Virginia / North Carolina) using the eastern ''O. l. lignaria'' found them to prefer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toxicoscordion Paniculatum
''Toxicoscordion paniculatum'' is a species of flowering plant known by the common names foothill deathcamas, panicled death-camas, and sand-corn. It is widely distributed across much of the western United States, especially in the mountains and deserts of the Great Basin region west of the Rocky Mountains. It grows in many types of habitat, including sagebrush plateau, grasslands, forests, and woodlands, etc. ''Toxicoscordion paniculatum'' is a perennial wildflower growing from a brown or black bulb up to 5 centimeters long by 3 wide. The stem grows up to 70 centimeters long. The leaves are linear in shape, measuring up to 50 centimeters long. Most of the leaves are at the base of the stem and there may be a few reduced leaves above. The inflorescence is an open panicle of flowers, becoming dense at the tip. (The flower pictured here appears to be of the close relative ''Toxicoscordion venenosum''; see Burke Museum external link for accurate descriptions.) The panicle contains ...

Death Camas Mining Bee Andrena Astragali THYG1
Death is the Irreversible process, irreversible cessation of all biological process, biological functions that sustain an organism. For organisms with a brain, death can also be defined as the irreversible cessation of functioning of the whole brain, including brainstem, and brain death is sometimes used as a legal definition of death. The remains of a former organism normally begin to Decomposition, decompose shortly after death. Death is an inevitable process that eventually occurs in Biological immortality, almost all organisms. Death is generally applied to whole organisms; the similar process seen in individual components of an organism, such as cells or tissues, is necrosis. Something that is not considered an organism, such as a virus, can be physically destroyed but is not said to die. As of the early 21st century, over 150,000 humans die each day, with ageing being by far the most common cause of death. Many cultures and religions have the idea of an afterlife, and a ...

Andrena Fulvida
''Andrena'' is a genus of bees in the family Andrenidae. With over 1,500 species, it is one of the largest genera of animals. It is a strongly monophyletic group that is difficult to split into more manageable divisions; currently, ''Andrena'' is organized into 104 subgenera. It is nearly worldwide in distribution, with the notable exceptions of Oceania and South America. Bees in this genus are commonly known as mining bees due to their ground-nesting lifestyle. Morphology ''Andrena'' are generally medium-sized bees; body length ranges between 8 and 17 mm with males being smaller and more slender than females. Most are black with white to tan hair, and their wings have either two or three submarginal cells. They carry pollen mainly on femoral scopal hairs, but many ''Andrena'' have an additional propodeal corbicula for carrying some pollen on their thorax.C. D. Michener (2007) ''The Bees of the World'', 2nd Edition, Johns Hopkins University Press. They can be dist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
