Delhi Sands Flower-loving Fly
The Delhi Sands flower-loving fly (''Rhaphiomidas terminatus abdominalis'') is a subspecies of mydid fly in the genus '' Rhaphiomidas''. It was the first fly added to the Endangered Species List in the United States. This subspecies is restricted to the Delhi Sand Dunes formation, an area of ancient inland dunes in Southern California. Originally, the habitat area consisted of about . However, only a few hundred acres, or about 2% of the original habitat area, remains undeveloped.U.S. Fish and Wildlife Service (USFWS). 1997.

Mydidae
The Mydidae (sometimes misspelled as Mydaidae), or Mydas flies, are a cosmopolitan family of flies. It is a small family, with about 471 species described. They are generally large in size, including the largest known fly, '' Gauromydas heros'' ( syn. ''Mydas heros''). Many of the species, in addition to their large size, are mimics of stinging hymenopterans, especially wasps. Most mydids are found in arid and semiarid regions of the world, but they are also found in other habitats. Biology Little is known about their biology, though Zikan reported the larvae of ''Gauromydas heros'' live in the subterranean detritus "pans" of ''Atta'' ants in southern Brazil, where they appear to be feeding on detritivorous Dynastinae ('' Coelosis'' spp.) larvae. In the U.S., '' Mydas brunneus, Mydas clavatus'', and ''Mydas tibialis'' larvae are predatory on deadwood-feeding scarab beetle larvae (''Osmoderma'' spp.) and can be found in standing and downed trees with extensive heart rot. Others (e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proboscis
A proboscis () is an elongated appendage from the head of an animal, either a vertebrate or an invertebrate. In invertebrates, the term usually refers to tubular mouthparts used for feeding and sucking. In vertebrates, a proboscis is an elongated nose or snout. Etymology First attested in English in 1609 from Latin , the latinisation of the Ancient Greek (), which comes from () 'forth, forward, before' + (), 'to feed, to nourish'. The plural as derived from the Greek is , but in English the plural form ''proboscises'' occurs frequently. Invertebrates The most common usage is to refer to the tubular feeding and sucking organ of certain invertebrates such as insects (e.g., moths, butterflies, and mosquitoes), worms (including Acanthocephala, proboscis worms) and gastropod molluscs. Acanthocephala The Acanthocephala or thorny-headed worms, or spiny-headed worms are characterized by the presence of an eversible proboscis, armed with spines, which it uses to pierce and ...

Argentine Ant
The Argentine ant (''Linepithema humile''), formerly ''Iridomyrmex humilis'', is an ant native to northern Argentina, Uruguay, Paraguay, Bolivia and southern Brazil. It is an invasive species that has been established in many Mediterranean climate areas, inadvertently introduced by humans to many places, including South Africa, New Zealand, Japan, Easter Island, Australia, Europe, Hawaii, and the continental United States. Description The worker ants are long and can easily squeeze through cracks and holes as small as in size. Queens are long, much smaller than other species of ants. These ants will set up quarters in the ground, in cracks in concrete walls, in spaces between boards and timbers, even among belongings in human dwellings. In natural areas, they generally nest shallowly in loose leaf litter or beneath small stones, due to their poor ability to dig deeper nests. However, if a deeper nesting ant species abandons their nest, Argentine ant colonies will readily ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heterotheca Grandiflora
''Heterotheca grandiflora'' is a species of flowering plant in the family Asteraceae known by the common name silk-grass goldenaster or telegraphweed. It is native to the southwestern United States ( California, Nevada, Utah, Arizona) and northwestern Mexico ( Baja California), but it can be found in other areas as an introduced species, such as Hawaii.

Eriogonum Fasciculatum
''Eriogonum fasciculatum'' is a species of wild buckwheat known by the common names California buckwheat and flat-topped buckwheat. Characterized by small, white and pink flower clusters that give off a cottony effect, this species grows variably from a patchy mat to a wide shrub, with the flowers turning a rusty color after blooming. This plant is of great benefit across its various habitats, providing an important food resource for a diversity of insect and mammal species. It also provides numerous ecosystem services for humans, including erosion control, post-fire mitigation, increases in crop yields when planted in hedgerows, and high habitat restoration value.Montalvo, A.

Mesozoic Era
The Mesozoic Era ( ), also called the Age of Reptiles, the Age of Conifers, and colloquially as the Age of the Dinosaurs is the second-to-last Era (geology), era of Earth's Geologic time scale, geological history, lasting from about , comprising the Triassic, Jurassic and Cretaceous Period (geology), Periods. It is characterized by the dominance of archosaurian reptiles, like the dinosaurs; an abundance of conifers and ferns; a hot Greenhouse and icehouse earth, greenhouse climate; and the tectonic break-up of Pangaea. The Mesozoic is the middle of the three eras since Cambrian explosion, complex life evolved: the Paleozoic, the Mesozoic, and the Cenozoic. The era began in the wake of the Permian–Triassic extinction event, the largest well-documented mass extinction in Earth's history, and ended with the Cretaceous–Paleogene extinction event, another mass extinction whose victims included the non-avian dinosaurs, Pterosaur, pterosaurs, Mosasaur, mosasaurs, and Plesiosaur, ples ...

Gondwana
Gondwana () was a large landmass, often referred to as a supercontinent, that formed during the late Neoproterozoic (about 550 million years ago) and began to break up during the Jurassic period (about 180 million years ago). The final stages of break-up, involving the separation of Antarctica from South America (forming the Drake Passage) and Australia, occurred during the Paleogene. Gondwana was not considered a supercontinent by the earliest definition, since the landmasses of Baltica, Laurentia, and Siberia were separated from it. To differentiate it from the Indian region of the same name (see ), it is also commonly called Gondwanaland. Gondwana was formed by the accretion of several cratons. Eventually, Gondwana became the largest piece of continental crust of the Palaeozoic Era, covering an area of about , about one-fifth of the Earth's surface. During the Carboniferous Period, it merged with Laurasia to form a larger supercontinent called Pangaea. Gondwana (and Pan ...
