Oliarus Polyphemus
''Oliarus polyphemus'', the Hawai'i cave planthopper,Howarth, Francis G. "Community structure and niche differentiation in Hawaiian lava tubes." ''US/IBP synthesis series'' (1981). is a species of ''Oliarus (planthopper), Oliarus'' planthopper endemic to the island of Hawaii (island), Hawai'i, where it inhabits lava tube, lava tubes and crevice networks embedded in solidified lava flows. Description ''Oliarus polyphemus'' is completely pale and unpigmented. It has no eyes and as such is completely blind. Individuals range from 3.2-5mm in length, with females being larger than males. Adults are flightless. Distribution and habitat ''Olarius polyphemus'' is only found on the island of Hawai'i. It is thought to live primarily in a vast network of underground cooling cracks formed when pahoehoe lava from the island's various volcanoes solidified. This crevice habitat is thought to be the primary habitat of ''O. polyphemus'' and other Hawai'i cave endemic arthropods, but individuals o ...

Hawaii (island)
Hawaii is the List of islands of the United States by area, largest island in the United States, located in the Hawaii, state of Hawaii, the southernmost state in the union. It is the southeasternmost of the Hawaiian Islands, a chain of volcanic islands in the Pacific Ocean, North Pacific Ocean. With an area of , it has 63% of the Hawaiian archipelago's combined landmass. However, it has only 13% of the archipelago's population. The island of Hawaii is the third largest island in Polynesia, behind the North Island, North and South Islands of New Zealand. The island is often referred to as the Island of Hawaii or Hawaii Island to distinguish it from the state. It is also referred to as The Big Island, due to its size relative to the other islands. In Hawaiian language, Hawaiian, the island is sometimes called ''Moku o Keawe''. The word ''keawe'' has several meanings. One definition, "southern cross", is said to be the name of an ancient chief. Another definition is "the bearer". ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lava Tube
A lava tube, more rarely called a pyroduct, is a 'roofed conduit through which molten lava travels away from its vent'. If lava in the tube drains out, it will leave an empty cave. Lava tubes are common in low-viscosity volcanic systems. Lava tubes are important as they are able to transport molten lava much further away from the eruptive vent than lava channels. A tube-forming lava flow can emplace on longer distance due to the presence of a solid crust protecting the molten lava from atmospheric cooling. Lava tubes are often considered when preparing hazard maps or managing an eruptive crisis. Formation A lava tube is a type of lava cave formed when a low-viscosity lava flow develops a continuous and hard crust, which thickens and forms a roof above the still-flowing lava stream. Three main formation mechanisms have been described: (1) roofing over a lava channel, (2) pāhoehoe lobe extension or (3) lava flow inflation. # When it erupts from a vent, lava usually flow ...

Pahoehoe
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is often also called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. Etymology The word ''lava'' comes from Italian and is probably derived from the Latin word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaumana Cave
Kaumana Cave is a lava tube created by a 1881 lava flow from Mauna Loa. The tube has been surveyed at 2.026 miles (2197 m) long making it the 57th longest lava tube in the world. The cave is located on the island of Hawaiʻi near the city of Hilo. A collapsed skylight provides easy access to two of the tube's entrances which became a tourist attraction. Some parts of the tube are located under private property, and so are some of the entrances. Many natural features, such as the stalagmites and the stalactites have since been broken off by tourists as souvenirs.

Mauna Loa
Mauna Loa (, ; ) is one of five volcanoes that form the Island of Hawaii in the U.S. state of Hawaii in the Pacific Ocean. Mauna Loa is Earth's largest active volcano by both mass and volume. It was historically considered to be the largest volcano on Earth until the submarine mountain Tamu Massif was discovered to be larger. Mauna Loa is a shield volcano with relatively gentle slopes, and a volume estimated at , although its peak is about lower than that of its neighbor, Mauna Kea. Lava eruptions from Mauna Loa are silica-poor and very fluid, and tend to be non-explosive. Mauna Loa has likely been erupting for at least 700,000 years, and may have emerged above sea level about 400,000 years ago. Some dated rocks are 470,000 years old. The volcano's magma comes from the Hawaii hotspot, which has been responsible for the creation of the Hawaiian Island chain over tens of millions of years. The slow drift of the Pacific Plate will eventually carry Mauna Lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metrosideros Polymorpha
''Metrosideros polymorpha'', the ''ōhia lehua'',; is a species of flowering evergreen tree in the Myrtus, myrtle family, Myrtaceae, that is Endemism, endemic to the six largest Hawaiian Islands, islands of Hawaii, Hawaii. It is a member of the diverse ''Metrosideros'' genus, which are widespread over the southwest Pacific. It is the state tree of Hawai'i. It is a highly variable tree, being tall in favorable situations, and a much smaller prostrate shrub when growing in Hawaiian tropical rainforests#Bogs, boggy soils or directly on basalt. It produces a brilliant display of flowers, made up of a mass of stamens, which can range from fiery red to yellow. Many native Hawaiian traditions refer to the tree and the forests it forms as sacred to Pele (deity), Pele, the volcano goddess, and to Laka, the goddess of hula. Ōhia trees grow easily on lava, and are usually the first plants to grow on new lava flows. ''Metrosideros polymorpha'' is commonly called a ''lehua'' tree, or an ' ...

Pupa
A pupa (; : pupae) is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their life cycle, the stages thereof being egg, larva, pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect's hormones, especially juvenile hormone, prothoracicotropic hormone, and ecdysone. The act of becoming a pupa is called pupation, and the act of emerging from the pupal case is called eclosion or emergence. The pupae of different groups of insects have different names such as ''chrysalis'' for the pupae of butterflies and ''tumbler'' for those of the mosquito family. Pupae may further be enclosed in other structures such as cocoons, nests, or shells. Position in life cycle The pupal stage follows the larval stage, or in some cases a prepupal stage, and precedes adulthood ('' imago'') in insects with compl ...

Insects Described In 1973
Insects (from Latin ') are hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes, and a pair of antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a brain and a ventral nerve cord. Most insects reproduce by laying eggs. Insects breathe air through a system of paired openings along their sides, connected to small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in vessels, and some circulates in an open hemocoel. Insect vision is mainly through their compound eyes, with additional small ocelli. Many insects can hear, using tympanal organs, which may be on the legs or other parts of the body. The ...
