Tachypompilus Unicolor
The red-tailed spider hunter (''Tachypompilus unicolor'') is a species of spider wasp from western North America. Description Especially in the subspecies ''T. u. cerinus'', the body is often entirely red, with yellow, dark-margined wings. Distribution It is found in Southern California, including the northern Baja California and the Channel Islands, north to the Okanagan Valley, southern British Columbia, eastwards through southwestern Idaho to western South Dakota and northern Utah. Biology Adults of ''T. unicolor'' feed at honeydew secretions and flowers. Females have been captured at honeydew from galls of '' Disholcapsis eldoradensis'' on '' Quercus lobata'' and at flowers of '' Asclepias erosa'', ''Baccharis sarothroides'', ''Chrysothamnus'' sp., '' Lepidospartum squamatum'', and '' Wislizenia refracta''. Males have been taken on the flowers of ''Calochortus catalinae'', '' Hemizonia fasciculata'', '' Rhamnus californica'', and ''Xanthium spinosum''. Both males and fem ...

Nathan Banks
Nathan Banks (April 13, 1868 – January 24, 1953) was an American entomologist noted for his work on Neuroptera, Megaloptera, Hymenoptera, and Acarina (mites). He started work on mites in 1880 with the USDA. In 1915 he authored the first comprehensive English handbook on mites: ''A Treatise on the Acarina, Or Mites'' (Smithsonian Institution, Proceedings Of The United States National Museum, 1905, 114 pages). Banks left the USDA in 1916 to work at the Museum of Comparative Zoology (MCZ) where he did further work on Hymenoptera, Arachnida and Neuroptera. He was elected a Fellow of the American Academy of Arts and Sciences in 1922. In 1924, he spent about two months in Panama, through kindness of Dr. Thomas Barbour Thomas Barbour (August 19, 1884 – January 8, 1946) was an American herpetologist.

Asclepias Erosa
''Asclepias erosa'' is a species of milkweed known commonly as desert milkweed. It is native to southern California, Arizona, and northern Baja California, where it is most abundant in the desert regions.

Each flower has thick, reflexed corollas beneath a flower center composed of rounded, horned filaments. Uses The plant is filled with a viscous sap that was roasted to a solid and enjoyed as a sort of chewing gum by local Native American groups. Researchers in Bard, California tested the plant as a potential source of natural rubber in 1935. Butterflies ''Asclepias erosa'' is a specific monarch butterfly food and habitat In ecology, ...

Eriogonum Fasciculatum
''Eriogonum fasciculatum'' is a species of wild buckwheat known by the common names California buckwheat and flat-topped buckwheat. Characterized by small, white and pink flower clusters that give off a cottony effect, this species grows variably from a patchy mat to a wide shrub, with the flowers turning a rusty color after blooming. This plant is of great benefit across its various habitats, providing an important food resource for a diversity of insect and mammal species. It also provides numerous ecosystem services for humans, including erosion control, post-fire mitigation, increases in crop yields when planted in hedgerows, and high habitat restoration value.Montalvo, A.

Cicuta
''Cicuta'', commonly known as water hemlock, is a genus of four species of highly poisonous plants in the family Apiaceae. They are perennial herbaceous plants which grow up to tall, having distinctive small green or white flowers arranged in an umbrella shape (umbel). Plants in this genus may also be referred to as cowbane or poison parsnip. ''Cicuta'' is native to temperate regions of the Northern Hemisphere, mainly North America and Europe, typically growing in wet meadows, along streambanks and other wet and marshy areas. These plants bear a close resemblance to other members in the family Apiaceae and may be confused with a number of edible or poisonous plants. The common name hemlock may also be confused with poison hemlock ('' Conium maculatum''), or with the Hemlock tree. Water hemlock is considered one of North America's most toxic plants, being highly poisonous to humans. Three members of the genus contain a toxin named cicutoxin which causes central nervous system st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atriplex Semibaccata
Atriplex semibaccata, commonly known as Australian saltbush, berry saltbush, or creeping saltbush, is a species of flowering plant in the family Amaranthaceae and is endemic to Australia. It is a perennial herb native to Western Australia, South Australia, Queensland and New South Wales, but has been introduced into other states and to overseas countries. It flowers and fruits in spring, and propagates from seed when the fruit splits open. This species of saltbush is adapted to inconsistent rainfall, temperature and humidity extremes and to poor soil. It is used for rehabilitation, medicine, as a cover crop and for fodder. Its introduction to other countries has had an environmental and economic impact on them. Description ''Atriplex semibaccata'' is a taproot perennial herb, that has prostrated and decumbent characteristics. Native to Australia and widespread in all mainland Australian states, ''A. semibaccata'' thrives in harsh and saline conditions. ''A. semibaccata'' is ofte ...

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] |
Extrafloral Nectary
Nectar is a sugar-rich liquid produced by plants in glands called nectaries or nectarines, either within the flowers with which it attracts pollination, pollinating animals, or by extrafloral nectaries, which provide a nutrient source to animal Mutualism (biology), mutualists, which in turn provide plant defense against herbivory#Indirect defenses, herbivore protection. Common nectar-consuming pollinators include mosquitoes, hoverfly, hoverflies, wasps, bees, butterfly, butterflies and moths, hummingbirds, honeyeaters and Bat#Fruit and nectar, bats. Nectar plays a crucial role in the foraging economics and evolution of nectar-eating species; for example, nectar foraging behavior is largely responsible for the divergent evolution of the African honey bee, African bee, ''A. m. scutellata'' and the western honey bee. Nectar is an economically important substance as it is the sugar source for honey. It is also useful in agriculture and horticulture because the adult stages of so ...
