Paracantha Gentilis
''Paracantha gentilis'' is a species of tephritid or fruit fly in the genus ''Paracantha'' of the family Tephritidae. It has a widespread distribution throughout the Western United States, and has also been found as far south as Mexico and Costa Rica. It most closely resembles '' Paracantha culta'', which is widespread in the Southeastern United States, but ''P. gentilis'' can be distinguished by having smaller spots on the head. Taxonomic history ''Paracantha gentilis'' was first described by Erich Martin Hering in 1940 from a pair of male and female specimens collected in Wyoming. In the same publication, he described ''Paracantha sobrina'' from a single female specimen collected in Costa Rica. The following year, John Russell Malloch revised the genus ''Paracantha'', and described three new species: ''P. mimetica, P. mimetica elongata,'' and ''P. mexicana''. These descriptions all largely relied on wing pattern characters rather than terminalia. In 1953, Martin Ladislau Acz� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Overwintering
Overwintering is the process by which some organisms pass through or wait out the winter season, or pass through that period of the year when "winter" conditions (cold or sub-zero temperatures, ice, snow, limited food supplies) make normal activity or even survival difficult or near impossible. In some cases "winter" is characterized not necessarily by cold but by dry conditions; passing through such periods could likewise be called overwintering. Hibernation and migration are the two major ways in which overwintering is accomplished. Animals may also go into a state of reduced physiological activity known as torpor. Overwintering occurs in several classes of lifeform. Insects In entomology, overwintering is how an insect passes the winter season. Many insects overwinter as adults, pupae, or eggs. This can be done inside buildings, under tree bark, or beneath fallen leaves or other plant matter on the ground, among other places. All such overwintering sites shield the in ...

Cirsium
''Cirsium'' is a genus of perennial and biennial flowering plants in the Asteraceae, one of several genera known commonly as thistles. They are more precisely known as plume thistles. These differ from other thistle genera ('' Carduus'', ''Silybum'' and '' Onopordum'') in having feathered hairs to their achenes. The other genera have a pappus of simple unbranched hairs. They are mostly native to Eurasia and northern Africa, with about 60 species from North America (although several species have been introduced outside their native ranges). Thistles are known for their effusive flower heads, usually purple, rose or pink, also yellow or white. The radially symmetrical disc flowers are at the end of the branches and are visited by many kinds of insects, featuring a generalised pollination syndrome. They have erect stems and prickly leaves, with a characteristic enlarged base of the flower which is commonly spiny. The leaves are alternate, and some species can be slightly hairy ...

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more t ...
