Chionodes Trichostola
''Chionodes trichostola'' is a moth in the family Gelechiidae. It is found in North America, where it has been recorded from south-western British Columbia to California, Utah, Colorado, Arizona and Texas. The wingspan is about 19 mm for males and 16 mm for females. The forewings are brown irregularly suffused with rather dark fuscous irroration and with a small blackish linear mark beneath the costa near the base. There is an elongate black spot on the base of the dorsum and an oblique streak from the costa to the plical stigma, obscurely indicated by dark suffusion with two small spots of blackish suffusion. The stigmata are cloudy, blackish, with the plical very obliquely before the first discal which tends to form an oblique mark. There are two or three whitish scales beyond this and before the second and there is also an angulated transverse streak of brown ground colour at three-fourths. The hindwings are grey. The larvae feed on '' Quercus chrysolepis'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moth
Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. Differences between butterflies and moths While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.Scoble, MJ 1995.

Quercus Douglasii
''Quercus douglasii'', known as blue oak, is a species of oak endemic to (and found only in) California, common in the Coast Ranges and the foothills of the Sierra Nevada. It is California's most drought-tolerant deciduous oak, and is a dominant species in the blue oak woodland ecosystem. It is occasionally known as mountain oak and iron oak. Description ''Quercus douglasii'' is a medium-sized tree with sparse foliage, generally tall, with a trunk in diameter at breast height. Trunks are typically solitary, but some trees have multiple trunks. The tallest recorded specimen was found in Alameda County, at . The trees grow slowly, about per year. Individual trees over 500 years old have been recorded. The bark is light gray with many medium-sized dark cracks. The blue-green leaves are tough and leathery, deciduous, long, and entire or shallowly lobed. The acorns are long, with a moderately sweet kernel, and mature in 6–7 months from pollination.

Sorbus
''Sorbus'' is a genus of over 100 species of trees and shrubs in the rose family, Rosaceae. Species of ''Sorbus'' (''s.l.'') are commonly known as whitebeam, rowan ( mountain-ash) and service tree. The exact number of species is disputed depending on the circumscription of the genus, and also due to the number of apomictic microspecies, which some treat as distinct species, but others group in a smaller number of variable species.

Quercus Dumosa
''Quercus dumosa'' is a species of plant in the family Fagaceae, belonging to the white oak section of the oak genus (''Quercus''). This tree goes by the common names coastal sage scrub oak and Nuttall's scrub oak. Description ''Quercus dumosa'' is an evergreen shrub growing 1 to 3 metres (40–120 inches or 3–10 feet) tall from a large, deep root network. The leaves have spiny or toothed edges. The fruit is an acorn up to wide. Some individuals produce large crops of acorns, and some produce very few fruits. The acorns are dispersed by gravity as they fall from the tree, and by animals that pick them up, such as squirrels and jays. Animals eat them immediately or cache them for later. The acorns tend to germinate easily. Reproduction via seed generally occurs only in very moist years. Taxonomy The name ''Quercus dumosa'' was formerly widely applied to nearly all the scrub oaks of the white oak group of California and Baja California. The concept of this species has gradual ...

Quercus Wislizenii
''Quercus wislizeni'', known by the common name interior live oak, is an evergreen oak, highly variable and often shrubby, found in many areas of California in the United States continuing south into northern Baja California in Mexico. It generally occurs in foothills, being most abundant in the lower elevations of the Sierra Nevada, but also widespread in the Pacific Coast Ranges—where since 1980 it has been known as a separate species ''Quercus parvula''—and the San Gabriel Mountains. It was named for its collector, Friedrich Adolph Wislizenus (1810–1889). Description It is a large shrub or tree growing to tall, although where it is common in the low-elevation Sierra Nevada foothills it seldom exceeds . The dark-green leaves—appearing grayish from a distance—are usually small, long, thick, and often spiny-toothed at higher elevations, particularly on young trees. The male flowers are on catkins, the female flowers in leaf axils. The acorns are long, and mature the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus Lobata
''Quercus lobata'', commonly called the valley oak or roble, grows into the largest of California oaks. It is endemic to California, growing in interior valleys and foothills from Siskiyou County to San Diego County. Mature specimens may attain an age of up to 600 years. This deciduous oak requires year-round access to groundwater. Its thick, ridged bark is characteristic and resembles alligator hide. The valley oak's deeply lobed leaves assist in identification. Description The valley oak may surpass in height, with a sturdy trunk possibly exceeding in diameter. The "Henley Oak", in Covelo, California, is the tallest known valley oak, at . The branches have an irregular, spreading and arching appearance that produce a profound leafless silhouette in the clear winter sky. During autumn, the leaves turn a yellow to light orange color but become brown later in the season. In advancing age, the branches assume a drooping characteristic.

Quercus Kelloggii
''Quercus kelloggii'', the California black oak, also known as Kellogg oak, is an oak in the red oak section (genus ''Quercus'', section ''Lobatae'', series ''Agrifoliae''), native to western North America. Although genetically separated from them for more than 20 million years, its leaves (though not its fruit) are remarkably similar in appearance to several other members of the red oak section including the red oak (''Quercus rubra'') and the black oak (''Quercus velutina'') found in eastern and central North America. Description ''Quercus kelloggii'' typically grows from in height and from in diameter. Large trees may exceed in height and diameter, with the record holder measuring tall and thick (in the Siskiyou National Forest in Oregon). The species also grows in shrubby scrub-oak form on poor sites. In open areas, the crown is broad and rounded, with lower branches nearly touching the ground or forming a browse line. In closed stands, the crown is narrow and slender ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus Chrysolepis
''Quercus chrysolepis'', commonly termed canyon live oak, canyon oak, golden cup oak or maul oak, is a North American species of evergreen oak that is found in Mexico and in the western United States, notably in the California Coast Ranges. This tree is often found near creeks and drainage swales growing in moist cool microhabitats. Its leaves are a glossy dark green on the upper surface with prominent spines; a further identification arises from the leaves of canyon live oak being geometrically flat. Description ''Quercus chrysolepis'' is an evergreen tree with significant-sized spreading, horizontal branches, and a broad, rounded crown; it attains a height of 6–30 meters (20–100 feet) and often forms as a shrub. The trunk diameter typically ranges from . Exceptionally large specimens are found in the mountains of Southern California, and rank among the largest oaks in North America.

Gelechiidae
The Gelechiidae are a family of moths commonly referred to as twirler moths or gelechiid moths. They are the namesake family of the huge and little-studied superfamily Gelechioidea, and the family's taxonomy has been subject to considerable dispute. These are generally very small moths with narrow, fringed wings. The larvae of most species feed internally on various parts of their host plants, sometimes causing galls. Douglas-fir (''Pseudotsuga'') is a host plant common to many species of the family, particularly of the genus ''Chionodes'', which as a result is more diverse in North America than usual for Gelechioidea. By the late 20th century, over 900 genera with altogether more than 4,500 species were placed here, with about 650 genera known from North America alone. While these figures are certainly outdated, due to the many revisions to superfamily Gelechioidea and new descriptions of twirler moths, they still serve to show the enormous biodiversity contained in this import ...
