Bombus Sonorus
''Bombus sonorus'', commonly known as the Sonoran bumble bee, is a species of bumble bee in the family Apidae. It is found in Central America and western and southwestern North America. Considered uncommon, it is sometimes categorized as a subspecies of '' Bombus pensylvanicus''. Description The thorax of this bumblebee is predominantly yellow and it has a long tongue.

Thomas Say
Thomas Say (June 27, 1787 – October 10, 1834) was an American entomologist, conchologist, and Herpetology, herpetologist. His studies of insects and shells, numerous contributions to scientific journals, and scientific expeditions to Florida, Georgia, the Rocky Mountains, Mexico, and elsewhere made him an internationally known naturalist. Say has been called the father of American descriptive entomology and American conchology. He served as librarian for the Academy of Natural Sciences of Philadelphia, curator at the American Philosophical Society (elected in 1817), and professor of natural history at the University of Pennsylvania. Early life and education Born in Philadelphia into a prominent Religious Society of Friends, Quaker family, Thomas Say was the great-grandson of John Bartram, and the great-nephew of William Bartram. His father, Dr. Benjamin Say, was brother-in-law to another Bartram son, Moses Bartram. The Say family had a house, "The Cliffs" at Gray's Ferry Bridge, ...

Helianthus
''Helianthus'' () is a genus comprising about 70 species of annual and perennial flowering plants in the daisy family Asteraceae commonly known as sunflowers. Except for three South American species, the species of ''Helianthus'' are native to North America and Central America. The best-known species is the common sunflower (''Helianthus annuus''), whose round flower heads in combination with the ligules look like the Sun. This and other species, notably Jerusalem artichoke (''H. tuberosus''), are cultivated in temperate regions and some tropical regions, as food crops for humans, cattle, and poultry, and as ornamental plants. The species ''H. annuus'' typically grows during the summer and into early fall, with the peak growth season being mid-summer. Several perennial ''Helianthus'' species are grown in gardens, but have a tendency to spread rapidly and can become aggressive. On the other hand, the whorled sunflower, ''Helianthus verticillatus'', was listed as an endanger ... [...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 ...

Botta's Pocket Gopher
Botta's pocket gopher (''Thomomys bottae'') is a pocket gopher native to western North America. It is also known in some sources as valley pocket gopher, particularly in California. Both the specific and common names of this species honor Paul-Émile Botta, a naturalist and archaeologist who collected mammals in California in 1827 and 1828. Description Botta's pocket gopher is a medium-sized gopher, with adults reaching a length of , including a tail of . The overall dental formula is . Males are larger, with a weight of , compared with in the females. Male pocket gophers are widely believed to continue growing throughout their life. However, size variation would indicate that some males are predisposed to be larger than others, and the largest male may not be the oldest. Coloration is highly variable, and has been used to help distinguish some of the many subspecies; it may also change over the course of a year as the animals molt. Both albino and melanistic individuals have al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chrysothamnus
''Chrysothamnus'', known as rabbitbrush, rabbitbush, and chamisa, are a genus of shrubs in the family Asteraceae. The native distribution is in the arid western United States, Canada, and northern Mexico. It is known for its bright white or yellow flowers in late summer. ''Chrysothamnus'' may grow up to a tall shrub or subshrub, usually with woody stem bases. The leaves are alternate, sessile or with short petioles, with entire edges. The flowerheads are singular or in clusters. Each composite flower often has five to 6 (though sometimes upwards of 40) yellow disc florets and no ray florets.

Linaria
''Linaria'' is a genus of almost 200 species of flowering plants, one of several related groups commonly called toadflax. They are annuals and herbaceous perennials, and the largest genus in the Antirrhineae tribe of the plantain family Plantaginaceae. Taxonomy ''Linaria'' was traditionally placed in the family Scrophulariaceae. Phylogenetic analysis has now placed it in the vastly expanded family Plantaginaceae. Closely related genera include '' Nuttallanthus'' (American toadflaxes, recently split from ''Linaria''), ''Antirrhinum'' (snapdragons) and ''Cymbalaria'' (ivy-leaved toadflaxes).

Gossypium
''Gossypium'' () is a genus of flowering plants in the tribe Gossypieae of the mallow family, Malvaceae, from which cotton is harvested. It is native to tropical and subtropical regions of the Old and New Worlds. There are about 50 ''Gossypium'' species, making it the largest genus in the tribe Gossypieae, and new species continue to be discovered. The name of the genus is derived from the Arabic word ''goz'', which refers to a soft substance. Cotton is the primary natural fibre used by humans today, amounting to about 80% of world natural fibre production. Where cotton is cultivated, it is a major oilseed crop and a main protein source for animal feed. Cotton is thus of great importance for agriculture, industry and trade, especially for tropical and subtropical countries in Africa, South America and Asia. Consequently, the genus ''Gossypium'' has long attracted the attention of scientists. The origin of the genus ''Gossypium'' is dated to around 5–10 million years a ...

Bombus Nevadensis
''Bombus nevadensis'', the Nevada bumblebee, is a species of bumblebee. It is native to North America, where it occurs from Alaska to California in the west, and east to Wisconsin, and in Arizona, New Mexico, and Mexico. Description A bumblebee with a long proboscis (tongue) and a short, dense fur, the females (queens and workers) have an entirely black head, while the face and top of the head of the male are yellow. The thorax is yellow, sometimes with a hairless, black spot in the middle. The three first terga (abdominal segments) are yellow, while the rest of the abdomen is black. However, the tip of the tail is more or less red in the male. The average body length is for the queen, (worker) and (male). The black and gold bumblebee (''Bombus auricomus'') is sometimes considered a subspecies of this species, ''B. nevadensis auricomus''. Genetic and morphological evidence supports them as separate species.Hatfield, R., et al. 2015''Bombus nevadensis''.The IUCN Red List of T ...
