Callophrys Xami
''Callophrys xami'', commonly referred to as the xami hairstreak or green hairstreak, is a butterfly included in the subgenus ''Xamia'' and the genus ''Callophrys'' in the family Lycaenidae. It was described by Tryon Reakirt in 1867. Other common names for this species, depending on the region, include green hairstreak and elfin. ''C. xami'' is considered to be a very rare species of butterfly, and its typical range is in southern Arizona and Texas including down south to Guatemala. The juniper hairstreak and the silver-banded hairstreak butterflies are similar species, but both differ significantly from ''C. xami'' in regards to the postmedian white line running across the butterfly wings. Description ''C. xami'' is a tailed species of butterfly that has a wingspan range of 2.38 to 2.86 cm. In appearance, the underside of the hindwing is yellowish green; the wing also contains the postmedian white line, which is the discernible colored line located posterior to the middle ...

Tryon Reakirt
Tryon Reakirt (April 21, 1844 – after 1871) was an American businessman and entomologist. He wrote several papers on butterflies and showed great promise in his field. However his career was cut short when financial and legal difficulties forced him to flee the country. Tryon Reakirt was born in Philadelphia on April 21, 1844, the son of John Reakirt and Elizabeth Catherine (Tryon) Reakirt. He attended Central High School of Philadelphia and then joined his father in the family business, the import and distribution of pharmaceuticals. In 1868 he invested in a new business, the Delaware Lead Works which manufactured white lead and other lead products. Reakirt joined the American Entomological Society of Philadelphia in 1863 at the age of nineteen. He became well known for his studies of the butterflies of the American tropics and the Asia Pacific region. In his career as an entomologist, Reakirt described many butterflies for the first time; for example, Reakirt described the '' ...

Pinophyta
Conifers () are a group of cone-bearing seed plants, a subset of gymnosperms. Scientifically, they make up the division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class, Pinopsida. All extant conifers are perennial woody plants with secondary growth. The majority are trees, though a few are shrubs. Examples include cedars, Douglas-firs, cypresses, firs, junipers, kauri, larches, pines, hemlocks, redwoods, spruces, and yews.Campbell, Reece, "Phylum Coniferophyta". ''Biology''. 7th ed. 2005. Print. p. 595. As of 2002, Pinophyta contained seven families, 60 to 65 genera, and more than 600 living species. Although the total number of species is relatively small, conifers are ecologically important. They are the dominant plants over large areas of land, most notably the taiga of the Northern Hemisphere, but also in similar cool climates in mountains further south. Boreal conifers have many wintertime adapta ...

Oviposition
The ovipositor is a tube-like organ used by some animals, especially insects, for the laying of eggs. In insects, an ovipositor consists of a maximum of three pairs of appendages. The details and morphology of the ovipositor vary, but typically its form is adapted to functions such as preparing a place for the egg, transmitting the egg, and then placing it properly. For most insects, the organ is used merely to attach the egg to some surface, but for many parasitic species (primarily in wasps and other Hymenoptera), it is a piercing organ as well. Some ovipositors only retract partly when not in use, and the basal part that sticks out is known as the scape, or more specifically oviscape, the word ''scape'' deriving from the Latin word , meaning "stalk" or "shaft". In insects Grasshoppers use their ovipositors to force a burrow into the earth to receive the eggs. Cicadas pierce the wood of twigs with their ovipositors to insert the eggs. Sawflies slit the tissues of ...

Crassulaceae
The Crassulaceae (, from Latin ''crassus'', thick), also known as the crassulas, the stonecrops or the orpine family, are a diverse Family (biology), family of dicotyledon angiosperms primarily characterized by succulent leaves and a form of photosynthesis known as crassulacean acid metabolism (CAM), in which plants photosynthesize in the daytime and exchange gases during the cooler temperatures of the night. The blossoms of crassulas generally have five floral parts. Crassulaceae are usually herbaceous, though there are some subshrubs, and relatively few trees or aquatic plants. The Crassulaceae is a medium-sized, monophyletic family in the core eudicots clade, along with the order Saxifragales, whose diversity has made infrafamilial classification very difficult. The family includes approximately 1,400 species and 34–35 genera—depending on the circumscription of the genus ''Sedum''—distributed over three subfamilies. Members of the Crassulaceae are found worldwide, though ...

Genera
Genus (; : genera ) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demonstrate both monophyly and validity as a separate lineag ...

Sedum
''Sedum'' is a large genus of flowering plants in the family Crassulaceae, members of which are commonly known as stonecrops. The genus has been described as containing up to 600 species, subsequently reduced to 400–500. They are leaf succulents found primarily in the Northern Hemisphere, but extending into the southern hemisphere in Africa and South America. The plants vary from annual and creeping herbs to shrubs. The plants have water-storing leaves. The flowers usually have five petals, seldom four or six. There are typically twice as many stamens as petals. Various species formerly classified as ''Sedum'' are now in the segregate genera '' Hylotelephium'' and ''Rhodiola''. Well-known European species of ''Sedum'' are '' Sedum acre'', '' Sedum album'', '' Sedum dasyphyllum'', and '' Sedum hispanicum''. Description ''Sedum'' is a genus that includes annual, biennial, and perennial herbs. They are characterised by succulent leaves and stems. The extent of morphologic ...

Echeveria
''Echeveria'' is a large genus of flowering plants in the family (biology), family Crassulaceae, native plant, native to semi-desert areas of Central America, Mexico and northwestern South America. Description Echeveria plants are evergreen. Flowers on short stalks (cymes) arise from compact rosettes of succulent plant, succulent fleshy, often brightly coloured leaves. Species are polycarpic, meaning that they may flower and set seed many times over the course of their lifetimes. Often, numerous offset (botany), offsets are produced, and are commonly known as "hen and chicks", which can also refer to other genera, such as ''Sempervivum'', that are significantly different from ''Echeveria''. Many species of ''Echeveria'' serve important environmental roles, such as those of host plants for butterflies. For example, the butterfly ''Callophrys xami'' uses several species of ''Echeveria'', such as ''Echeveria gibbiflora'', as suitable host plants. Even more, these plants are integra ...

Host Organism
In biology and medicine, a host is a larger organism that harbours a smaller organism; whether a parasitic, a mutualistic, or a commensalist ''guest'' (symbiont). The guest is typically provided with nourishment and shelter. Examples include animals playing host to parasitic worms (e.g. nematodes), cells harbouring pathogenic (disease-causing) viruses, or a bean plant hosting mutualistic (helpful) nitrogen-fixing bacteria. More specifically in botany, a host plant supplies food resources to micropredators, which have an evolutionarily stable relationship with their hosts similar to ectoparasitism. The host range is the collection of hosts that an organism can use as a partner. Symbiosis Symbiosis spans a wide variety of possible relationships between organisms, differing in their permanence and their effects on the two parties. If one of the partners in an association is much larger than the other, it is generally known as the host. In parasitism, the parasite benefits a ...

Competition (biology)
Competition is an Biological interaction, interaction between organisms or species in which both require one or more Resource (biological), resources that are in Limiting factor, limited supply (such as food, water, or Territory (animal), territory). Competition lowers the Fitness (biology), fitness of both organisms involved since the presence of one of the organisms always reduces the amount of the resource available to the other. In the study of community ecology, competition within and between members of a species is an important biological interaction. Competition is one of many interacting Biotic component, biotic and Abiotic component, abiotic factors that affect Community (ecology), community structure, species diversity, and population dynamics (shifts in a population over time). There are three major Mechanism (biology), mechanisms of competition: interference, exploitation, and apparent competition (in order from most direct to least direct). Interference and exploitat ...

Courtship Display
A courtship display is a set of display behaviors in which an animal, usually a male, attempts to attract a mate; the mate exercises choice, so sexual selection acts on the display. These behaviors often include ritualized movement ("dances"), vocalizations, mechanical sound production, or displays of beauty, strength, or agonistic ability. Male display In some species, males will perform ritualized movements to attract females. The male six-plumed bird-of-paradise ( ''Parotia lawesii'') exemplifies male courtship display with its ritualized " ballerina dance" and unique occipital and breast feathers that serve to stimulate the female visual system. In '' Drosophila subobscura,'' male courtship display is seen through the male's intricate wing scissoring patterns and rapid sidestepping. These stimulations, along with many other factors, result in subsequent copulation or rejection. In other species, males may exhibit courtship displays that serve as both visual and auditor ...
