Olycella Subumbrella
''Melitara subumbrella'' is a species of snout moth in the genus ''Melitara''. It was described by Harrison Gray Dyar Jr. in 1925. It is widespread in western North America, from southern Alberta and Saskatchewan to southern Arizona, central Texas, southern New Mexico and south-eastern California. The wingspan is 35–52 mm. The forewings are long, narrow and uniformly gray or brownish gray, generally with dark lines along the veins. The hindwings are broad and white, often with grayish or grayish-brown margins. Adults are on wing from March to May. A second generation may occur on some locations, with adults on wing from October to November. The larvae feed on '' Opuntia basilaris'', ''Opuntia ficus-indica'', ''Opuntia macrorhiza'' var. ''macrorhiza'', ''Opuntia atrispina'', ''Opuntia phaeacantha'', ''Opuntia polyacantha'' and ''Opuntia violaceae'' var. ''macrocentra''. Young larvae are gregarious and prefer to feed on cactus fruit.

Opuntia Ficus-indica
''Opuntia ficus-indica'', the Indian fig opuntia, fig opuntia, or prickly pear, is a species of cactus that has long been a domesticated crop plant grown in agricultural economies throughout arid and semiarid parts of the world. ''O. ficus-indica'' is the most widespread and most commercially important cactus. It is grown primarily as a fruit crop, and also for the vegetable nopales and other uses. Cacti are good crops for dry areas because they efficiently convert water into biomass. ''O. ficus-indica'', as the most widespread of the long-domesticated cactuses, is as economically important as maize and blue agave in Mexico. ''Opuntia'' species hybridize easily, but the wild origin of ''O. ficus-indica'' is likely to have been in central Mexico, where its closest genetic relatives are found. Names Most culinary references to the "prickly pear" refer to this species. The Spanish name ''tuna'' is also used for the fruit of this cactus and for ''Opuntia'' in general; according to ...

Moths Of North America
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.

Instar
An instar (, from the Latin '' īnstar'', "form", "likeness") is a developmental stage of arthropods, such as insects, between each moult (''ecdysis''), until sexual maturity is reached. Arthropods must shed the exoskeleton in order to grow or assume a new form. Differences between instars can often be seen in altered body proportions, colors, patterns, changes in the number of body segments or head width. After shedding their exoskeleton (moulting), the juvenile arthropods continue in their life cycle until they either pupate or moult again. The instar period of growth is fixed; however, in some insects, like the salvinia stem-borer moth, the number of instars depends on early larval nutrition. Some arthropods can continue to moult after sexual maturity, but the stages between these subsequent moults are generally not called instars. For most insect species, an ''instar'' is the developmental stage of the larval forms of holometabolous (complete metamorphism) or nymphal ...

Gregarious
Sociality is the degree to which individuals in an animal population tend to associate in social groups (gregariousness) and form cooperative societies. Sociality is a survival response to evolutionary pressures. For example, when a mother wasp stays near her larvae in the nest, parasites are less likely to eat the larvae. Biologists suspect that pressures from parasites and other predators selected this behavior in wasps of the family Vespidae. This wasp behaviour evidences the most fundamental characteristic of animal sociality: parental investment. Parental investment is any expenditure of resources (time, energy, social capital) to benefit one's offspring. Parental investment detracts from a parent's capacity to invest in future reproduction and aid to kin (including other offspring). An animal that cares for its young but shows no other sociality traits is said to be ''subsocial''. An animal that exhibits a high degree of sociality is called a ''social animal''. T ...

Opuntia Violaceae
''Opuntia'', commonly called prickly pear or pear cactus, is a genus of flowering plants in the cactus family Cactaceae. Prickly pears are also known as ''tuna'' (fruit), ''sabra'', ''nopal'' (paddle, plural ''nopales'') from the Nahuatl word for the pads, or nostle, from the Nahuatl word for the fruit; or paddle cactus. The genus is named for the Ancient Greek city of Opus, where, according to Theophrastus, an edible plant grew and could be propagated by rooting its leaves. The most common culinary species is the Indian fig opuntia (''O. ficus-indica''). Description ''O. ficus-indica'' is a large, trunk-forming, segmented cactus that may grow to with a crown of over in diameter and a trunk diameter of . Cladodes (large pads) are green to blue-green, bearing few spines up to or may be spineless.

Opuntia Phaeacantha
''Opuntia phaeacantha'' is a species of prickly pear cactus known by the common names tulip prickly pear, Mojave prickly pear, and desert prickly pear found across the southwestern United States, lower Great Plains, and northern Mexico. The plant forms dense but localized thickets. Several varieties of this particular species occur, and it also hybridizes easily with other prickly pears, making identification sometimes tricky. Description ''Opuntia phaeacantha'' has a mounding habit of flattened green pads. The pads are protected by clusters of spines. Each cluster bearing 1-4 spines. The spines are brown, reddish-brown, or gray, and often over 3 cm in length. At the base of the spine cluster is a round tuft of easily detached brown bristles called Glochids. Glochids are also present on the fruit. This is the source for the plants common name "prickly pear". The flowers are bright yellow with a pale green center. Some plants produce yellow flowers with an orange-red center. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opuntia Atrispina
''Opuntia atrispina'' is a cactus species in the genus ''Opuntia ''Opuntia'', commonly called prickly pear or pear cactus, is a genus of flowering plants in the cactus family Cactaceae. Prickly pears are also known as ''tuna'' (fruit), ''sabra'', '' nopal'' (paddle, plural ''nopales'') from the Nahuatl word ...''. It has limited distribution in the United States. In Texas it can be found from near Uvalde to Del Rio/Langtry—a small strip of area just 50 miles long. Description The epithet of this species means "black-spined", denoting the fact that its spines are dark-brown to black at least in the lower part. The flowers on these small shrubs are special because they open pale yellow (sometimes almost white) and darken with age to rose. Thus, the plants can be adorned with flowers of multiple colors: cream, yellow, salmon, and rose. Newly opened flowers can even have a hint of green in the middle. The spines too are special because they are yellowish at the tips but dark ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opuntia Macrorhiza
''Opuntia macrorhiza'' is a common and widespread species of cactus with the common names plains pricklypear or prairie pricklypear or western pricklypear. It is found throughout the Great Plains of the United States, from Texas to Minnesota, and west into the Rocky Mountain states to New Mexico, Utah, and perhaps Idaho, with sporadic populations in the Mississippi and Ohio Valleys. It is also reported from northern Mexico in the states of Chihuahua, Sonora, Coahuila, Nuevo León, Durango, Tamaulipas, and San Luís Potosí., though all Arizona and Mexican records should be considered with caution due to confusion with other similar species. The species is cultivated as an ornamental in other locations. The species prefers well-drained, sandy or gravelly soils, mostly in grassland areas. It is one of the shorter species of the genus, rarely over 30 cm (1 foot) tall, spreading horizontally and forming wide clumps. Flowers are showy and bright yellow, often with red markings ...
