''Asteromyia gutierreziae'' is a species of gall midges in the family Cecidomyiidae. They are black, about 3-5mm long and found on upper leaves, lower leaves and the stem. They can cause galls, on such plants as '' Medranoa palmeri'' (Texas Desert Goldenrod), ''Baccharis angustifolia'', ''Baccharis sarothroides'', '' Gutierrezia californica'', ''Gutierrezia microcephala'', '' Gutierrezia sarothrae'' and ''Gymnosperma glutinosum ''Gymnosperma'' is a genus of North American flowering plants in the family Asteraceae.

Gall Midge
Cecidomyiidae is a family of flies known as gall midges or gall gnats. As the name implies, the larvae of most gall midges feed within plant tissue, creating abnormal plant growths called galls. Cecidomyiidae are very fragile small insects usually only in length; many are less than long. They are characterised by hairy wings, unusual in the order Diptera, and have long antennae. Some Cecidomyiids are also known for the strange phenomenon of paedogenesis in which the larval stage reproduces without maturing first. In some species, the daughter larvae consume the mother, while in others, reproduction occurs later on in the egg or pupa. More than 6,650 species and 830 genera are described worldwide, though this is certainly an underestimate of the actual diversity of this family. A DNA barcoding study published in 2016 estimated the fauna of Canada alone to be in excess of 16,000 species, hinting at a staggering global count of over 1 million cecidomyiid species that have ye ...

Galls
Galls (from the Latin , 'oak-apple') or ''cecidia'' (from the Greek , anything gushing out) are a kind of swelling growth on the external tissues of plants, fungi, or animals. Plant galls are abnormal outgrowths of plant tissues, similar to benign tumors or warts in animals. They can be caused by various parasites, from viruses, fungi and bacteria, to other plants, insects and mites. Plant galls are often highly organized structures so that the cause of the gall can often be determined without the actual agent being identified. This applies particularly to some insect and mite plant galls. The study of plant galls is known as cecidology. In human pathology, a gall is a raised sore on the skin, usually caused by chafing or rubbing. Causes of plant galls Insects and mites Insect galls are the highly distinctive plant structures formed by some herbivorous insects as their own microhabitats. They are plant tissue which is controlled by the insect. Galls act as both the habitat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baccharis Angustifolia
''Baccharis angustifolia'' (most commonly known as saltwater false willow or just false willow) is a species of North American plants in the family Asteraceae. It is native to the Southeastern United States from Louisiana to North Carolina. ''Baccharis angustifolia'' is a shrub sometimes as much as tall, with narrow, succulent leaves up to long. It is found on streambanks, in hammocks, and on coastal sand dunes A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, f ....

Baccharis Sarothroides
''Baccharis sarothroides'' is a North American species of flowering shrub known by the common names broom baccharis, desertbroom, greasewood, rosin-bush and groundsel in English and "escoba amarga" or "romerillo" in Spanish. This is a spreading, woody shrub usually sticky with glandular secretions along the primarily leafless green stems. The small, thick leaves are a few centimeters long and are absent much of the year, giving the shrub a spindly, twiggy appearance. It flowers abundantly with tiny green blooms on separate male and female plants. Native to the Sonoran Desert of northwestern Mexico (Baja California, Baja California Sur, Sinaloa, Sonora) and the Southwestern United States (southern California, Arizona, New Mexico, western Texas), it is common in gravelly dry soils and disturbed areas. Uses The Seri refer to desert broom as , and make a decoction by cooking the twigs. This drink is used to treat colds, sinus headache, and general sore achey ailments. The same ...

Gutierrezia Californica
''Gutierrezia californica'' is a North American species of flowering plant in the family Asteraceae known by the common names San Joaquin snakeweed and California matchweed. It is native to California and Arizona in the United States and Baja California in Mexico. It grows in sunny sandy or rocky areas in grasslands, scrub, or open woodlands. This is a small subshrub reaching up to about half a meter (20 inches) in height. It grows clumpy or gangly and generally erect stems in shades of gray and red which are lined with small linear green leaves. At the end of each branch of the stem is an inflorescence of one to three small flower heads A pseudanthium (Greek for "false flower"; ) is an inflorescence that resembles a flower. The word is sometimes used for other structures that are neither a true flower nor a true inflorescence. Examples of pseudanthia include flower heads, compos ... just a few millimeters wide.

Gutierrezia Microcephala
''Gutierrezia microcephala'' is a species of flowering plant in the family Asteraceae known by the common names sticky snakeweed, threadleaf snakeweed, threadleaf broomweed, and smallhead snakeweed. It is a subshrub native to the southwestern United States and northern Mexico, and can be found in arid grassland and desert sand dune habitats. It can be toxic to livestock in large quantities, due to the presence of saponins and high concentrations of selenium. Botanical description ''Gutierrezia microcephala'' is a small, resinous, perennial desert subshrub that is typically in height and less than in diameter. It is heavily branched, often causing it to be nearly spherical. New shoots and twigs are green to yellow in color, and older parts are brown and woody. The leaves are linear, threadlike, and alternate; long and wide. Along with the leaves, the stem tissue is photosynthetic, giving the plant a high photosynthetic capacity. ''G. microcephala'' typically flowers July t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gutierrezia Sarothrae
''Gutierrezia sarothrae'' is a species of flowering plant in the family Asteraceae known by the common names broom snakeweed, broomweed, snakeweed, and matchweed. It is a subshrub native to much of the western half of North America, from western Canada to northern Mexico, and can be found in a number of arid, grassland, and mountain habitats. It can be toxic to livestock in large quantities, due mainly to the presence of saponins. The species was utilized by various Native American groups for medicinal and other purposes. Description ''Gutierrezia sarothrae'' is a perennial subshrub that ranges from in height. The stems are green to brown, bushy, and herbaceous, and branch upwards from a woody base. The stems die back during dormancy, giving the plant its broom-like appearance. They range from smooth to having some short hairs, and may be resinous and therefore sticky when touched. As the stems are about the same length, this causes the plant to often appear domed or fan-shape ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cecidomyiinae
The Cecidomyiinae are a subfamily of flies often called gall midges or gall gnats.
