Cicada
The cicadas () are a superfamily, the Cicadoidea, of insects in the order Hemiptera (true bugs). They are in the suborder Auchenorrhyncha, along with smaller jumping bugs such as leafhoppers and froghoppers. The superfamily is divided into two families, the Tettigarctidae, with two species in Australia, and the Cicadidae, with more than 3,000 species Taxonomy (biology)#Taxonomic descriptions, described from around the world; many species remain undescribed. Cicadas have prominent eyes set wide apart, short antennae, and membranous front wings. They have an exceptionally loud song, produced in most species by the rapid buckling and unbuckling of drumlike tymbals. The earliest known fossil Cicadomorpha appeared in the Upper Permian period; extant species occur all around the world in temperate to tropical climates. They typically live in trees, feeding on watery sap from xylem tissue, and laying their eggs in a slit in the bark. Most cicadas are crypsis, cryptic. The vast majorit ...

Periodical Cicadas
The term periodical cicada is commonly used to refer to any of the seven species of the genus ''Magicicada'' of eastern North America, the 13- and 17-year cicadas. They are called periodical because nearly all individuals in a local population are developmentally synchronized and emerge in the same year. Although they are sometimes called " locusts", this is a misnomer, as cicadas belong to the taxonomic order Hemiptera (true bugs), suborder Auchenorrhyncha, while locusts are grasshoppers belonging to the order Orthoptera. ''Magicicada'' belongs to the cicada tribe Lamotialnini, a group of genera with representatives in Australia, Africa, and Asia, as well as the Americas. ''Magicicada'' species spend around 99.5% of their long lives underground in an immature state called a nymph. While underground the nymphs feed on xylem fluids from the roots of deciduous forest trees in the eastern United States. In the spring of their 13th or 17th year mature cicada nymphs emerge betwe ...

Magicicada Cassini
''Magicicada cassini'' (originally spelled ''cassinii'' ), known as the 17-year cicada, Cassin's periodical cicada or the dwarf periodical cicada, is a species of periodical cicada. It is endemic to North America. It has a 17-year life cycle but is otherwise indistinguishable from the 13-year periodical cicada ''Magicicada tredecassini''. The two species are usually discussed together as "cassini periodical cicadas" or "cassini-type periodical cicadas." Unlike other periodical cicadas, cassini-type males may synchronize their courting behavior so that tens of thousands of males sing and fly in unison. The species was first reported to the Academy of Natural Sciences of Philadelphia by Margaretta Morris in 1846. In 1852, the species was formally described by J. C. Fisher and given the specific name ''cassini'' in honour of John Cassin, an American ornithologist, whose own report was included by Fisher in his publication.

Hemiptera
Hemiptera (; ) is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs. They range in size from to around , and share a common arrangement of piercing-sucking mouthparts. The name "true bugs" is often limited to the suborder Heteroptera. Entomologists reserve the term ''bug'' for Hemiptera or Heteroptera,Gilbert Waldbauer. ''The Handy Bug Answer Book.'' Visible Ink, 1998p. 1. which does not include other arthropods or insects of other orders such as ants, bees, beetles, or butterflies. In some variations of English, all terrestrial arthropods (including non-insect arachnids, and myriapods) also fall under the colloquial understanding of ''bug''. Many insects with "bug" in their common name, especially in American English, belong to other orders; for example, the lovebug is a fly and the Maybug and ladybug are beetles. The term ...

Cicadidae
Cicadidae, the true cicadas, is the largest family of cicadas, with more than 3,200 species worldwide. The oldest known definitive fossils are from the Paleocene, a nymph from the Cretaceous Burmese amber has been attributed to the family, but could also belong to the Tettigarctidae. Description Cicadas are large insects characterized by their membranous wings, triangular-formation of three ocelli on the top of their heads, and their short, bristle-like antennae. Life cycle Cicadas are generally separated into two categories based on their adult emergence pattern. Annual cicadas remain underground as nymphs for two or more years and the population is not locally synchronized in its development, so that some adults mature each year or in most years. Periodical cicadas also have multiple-year life cycles but emerge in synchrony or near synchrony in any one location and are absent as adults in the intervening years.

Annual Cicada
Annual cicadas are North American Cicadidae species that appear every summer. The life cycle of a so-called annual cicada typically spans 2 to 5 years; they are "annual" only in the sense that members of the species reappear annually. The name is used to distinguish them from periodical cicada species, which occur only in Eastern North America, are developmentally synchronized, and appear in great swarms every 13 or 17 years. All other cicadas from all other biogeographic regions produce annual broods, so the distinction is not made outside of North America. Species called "annual cicada" include members of the genus '' Neotibicen'' ("dog-day cicadas"), ''Diceroprocta'', ''Neocicada'', and ''Okanagana ''Okanagana'' is a genus of cicadas in the family Cicadidae Cicadidae, the true cicadas, is the largest family of cicadas, with more than 3,200 species worldwide.

Tymbal
The tymbal (or timbal) is the corrugated exoskeletal structure used to produce sounds in insects. In male cicadas, the tymbals are membranes in the abdomen, responsible for the characteristic sound produced by the insect. In tiger moths, the tymbals are modified regions of the thorax, and produce high-frequency clicks. In lesser wax moths the left and right tymbals emit high frequency pulses that are used as mating calls. The paired tymbals of a cicada are located on the sides of the abdominal base. The "singing" of a cicada is not stridulation as in many other familiar sound-producing insects like crickets (where one structure is rubbed against another): the tymbals are regions of the exoskeleton that are modified to form a complex membrane with thin, membranous portions and thickened "ribs". These membranes vibrate rapidly, and enlarged chambers derived from the tracheae enable the cicada's body to be a resonance chamber, greatly amplifying the sound. Some cicadas pro ...

Tettigarctidae
The Tettigarctidae, known as the hairy cicadas, are a small relict (mostly extinct) family of primitive cicadas. Along with more than 20 extinct genera, Tettigarctidae contains a single extant genus, '' Tettigarcta'', with two extant species, one from southern Australia ('' T. crinita'') and one from the island of Tasmania ('' T. tomentosa''). Numerous fossil species have been described from the Late Triassic onwards. ''Tettigarcta'' are the closest living relatives of the true cicadas.

Insect
Insects (from Latin ') are pancrustacean 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 one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leafhopper
A leafhopper is the common name for any species from the family Cicadellidae. These minute insects, colloquially known as hoppers, are plant feeders that suck plant sap from grass, shrubs, or trees. Their hind legs are modified for jumping, and are covered with hairs that facilitate the spreading of a secretion over their bodies that acts as a water repellent and carrier of pheromones. They undergo a partial metamorphosis, and have various host associations, varying from very generalized to very specific. Some species have a cosmopolitan distribution, or occur throughout the temperate and tropical regions. Some are pests or vectors of plant viruses and phytoplasmas. The family is distributed all over the world, and constitutes the second-largest hemipteran family, with at least 20,000 described species. They belong to a lineage traditionally treated as infraorder Cicadomorpha in the suborder Auchenorrhyncha, but as the latter taxon is probably not monophyletic, many mod ...

Myanmar
Myanmar, ; UK pronunciations: US pronunciations incl. . Note: Wikipedia's IPA conventions require indicating /r/ even in British English although only some British English speakers pronounce r at the end of syllables. As John Wells explains, the English spellings of both Myanmar and Burma assume a non-rhotic variety of English, in which the letter r before a consonant or finally serves merely to indicate a long vowel: �mjænmɑː, ˈbɜːmə So the pronunciation of the last syllable of Myanmar as ɑːror of Burma as ɜːrməby some speakers in the UK and most speakers in North America is in fact a spelling pronunciation based on a misunderstanding of non-rhotic spelling conventions. The final ''r'' in ''Myanmar'' was not intended for pronunciation and is there to ensure that the final a is pronounced with the broad ''ah'' () in "father". If the Burmese name my, မြန်မာ, label=none were spelled "Myanma" in English, this would be pronounced at the end by al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
