Carbotriplurida
''Carbotriplura'' is a genus of insect from the Carboniferous of the Czech Republic. This genus contains one species, ''Carbotriplura kukalovae'', and is the only genus within the order Carbotriplurida. It was previously interpreted as a nymph of '' Bojophlebia'' during the former's description, however this was disproven in 1996 when it was found to be a separate order of apterygote (wingless) insects. A 2014 paper then re-examined it, finding it to be the sister clade to winged insects. Description ''Carbotriplura'' is a very large insect, reaching over 10 cm in length excluding the tail filaments. Its head is triangular in shape with large lateral (side) eyes. An isolated fragment of the left antenna is preserved, consisting of the scapus, pedicel, and the base of the flagellum with a small fragment further away. The scapus and pedicel are covered in hairs. While the individual segments of the flagellum are not preserved, the structure is at least as long as the rest of t ...

Bojophlebia
''Bojophlebia'' is an extinct genus of winged insect from the Pennsylvanian period of the Czech Republic. It includes only a single species, ''Bojophlebia prokopi'', and is the only member of the family Bojophlebiidae. ''Bojophlebia prokopi'' was first described in 1985 by Jarmila Kukalová-Peck, who originally described it as a large mayfly-like insect. This original interpretation has since been rejected. Most recently, ''B. prokopi'' has been treated as a member of the infraclass Hydropalaeoptera, which also includes the Odonatoptera (dragonflies, damselflies and extinct relatives) and Panephemeroptera (mayflies and extinct relatives). ''Bojophlebia'' is considered a sister group of all other members of the Hydropalaeoptera. A fossil that was described as a nymph of ''Bojophlebia'' is now considered to be a separate taxon, ''Carbotriplura kukalovae''. The original description interpreted structures such as eyes and antennae, however these structures cannot be confirmed after re ...

Insect
Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), 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 insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs. Insects Respiratory system of insects, breathe air through a system of Spiracle (arthropods), paired openings along their sides, connected to Trachea#Invertebrates, small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in ves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carboniferous Insects
The Carboniferous ( ) is a geologic period and system of the Paleozoic era that spans 60 million years, from the end of the Devonian Period Ma (million years ago) to the beginning of the Permian Period, Ma. It is the fifth and penultimate period of the Paleozoic era and the fifth period of the Phanerozoic eon. In North America, the Carboniferous is often treated as two separate geological periods, the earlier Mississippian and the later Pennsylvanian. The name ''Carboniferous'' means "coal-bearing", from the Latin ("coal") and ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern "system" names, it was coined by geologists William Conybeare and William Phillips in 1822, based on a study of the British rock succession. Carboniferous is the period during which both terrestrial animal and land plant life was well established. Stegocephalia (four-limbed vertebrates including true tetrapods), whose forerunners (tetrapodomor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coxoplectoptera
Coxoplectoptera or "chimera wings" is an extinct order of stem-group mayflies containing one family, Mickoleitiidae. Together with mayflies ( Ephemeroptera), Coxoplectoptera are assigned to the clade Heptabranchia. Two adult and more than 20 nymphal fossils of ''Mickoleitia'' have been scientifically described from Mesozoic outcrops, mainly from the Lower Cretaceous Crato Formation of Brazil (in total, around 40 fossil nymphs have been found). Both the winged adults and the aquatic nymphs were predators with raptorial forelegs, which are reminiscent to those of praying mantids. The nymphs had a peculiar freshwater shrimp-like habitus. Etymology The genus ''Mickoleitia'' and family Mickoleitiidae was named in honor of German zoologist Gerhard Mickoleit from the University of Tübingen, who was among the first proponents of Willi Hennig's " Phylogenetic Systematics". The scientific name of the order Coxoplectoptera refers to the prolonged coxal segment of the nymphal and adu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mayfly
Mayflies (also known as shadflies or fishflies in Canada and the upper Midwestern United States, as Canadian soldiers in the American Great Lakes region, and as up-winged flies in the United Kingdom) are aquatic insects belonging to the order Ephemeroptera. This order is part of an ancient group of insects termed the Palaeoptera, which also contains dragonflies and damselflies. Over 3,000 species of mayfly are known worldwide, grouped into over 400 genera in 42 families. Mayflies have ancestral traits that were probably present in the first flying insects, such as long tails and wings that do not fold flat over the abdomen. Their immature stages are aquatic fresh water forms (called "naiads" or "nymphs"), whose presence indicates a clean, unpolluted and highly oxygenated aquatic environment. They are unique among insect orders in having a fully winged terrestrial preadult stage, the subimago, which moults into a sexually mature adult, the imago. Mayflies "hatch" (emerge ...

Meganeura
''Meganeura'' is a genus of extinct insects from the Late Carboniferous (approximately 300 million years ago). It is a member of the extinct order Meganisoptera, which are closely related to and resemble dragonflies and damselflies (with dragonflies, damselflies and meganisopterans being part of the broader group Odonatoptera). Like other odonatopterans, they were predatory, with their diet mainly consisting of other insects. The genus belongs to the Meganeuridae, a family including other similarly giant dragonfly-like insects ranging from the Late Carboniferous to Middle Permian. With single wing length reaching and a wingspan about , ''M. monyi'' is one of the largest-known flying insect species. Fossils of ''Meganeura'' were first discovered in Late Carboniferous ( Stephanian) Coal Measures of Commentry, France in 1880. In 1885, French paleontologist Charles Brongniart described and named the fossil "''Meganeura''" (great-nerved), which refers to the network of vei ...

Cercus
Cerci (: cercus) are paired appendages usually on the rear-most segments of many arthropods, including insects and symphylans. Many forms of cerci serve as sensory organs, but some serve as pinching weapons or as organs of copulation. In many insects, they simply may be functionless vestigial structures. In basal arthropods, such as silverfish, the cerci originate from the eleventh abdominal segment. As segment eleven is reduced or absent in the majority of arthropods, in such cases, the cerci emerge from the tenth abdominal segment. It is not clear that other structures so named are homologous. In the Symphyla they are associated with spinnerets. Morphology and functions Most cerci are segmented and jointed, or filiform (threadlike), but some take very different forms. Some Diplura, in particular ''Japyx'' species, have large, stout forcipate (pincer-like) cerci that they use in capturing their prey. The Dermaptera, or earwigs, are well known for the forcipate cerci that most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archaeognatha
The Archaeognatha are an order of apterygotes, known by various common names such as jumping bristletails. Among extant insect taxa they are some of the most evolutionarily primitive; they appeared in the Middle Devonian period at about the same time as the arachnids. Specimens that closely resemble extant species have been found as both body and trace fossils (the latter including body imprints and trackways) in strata from the remainder of the Paleozoic Era and more recent periods. For historical reasons an alternative name for the order is Microcoryphia. Until the late 20th century the suborders Zygentoma and Archaeognatha comprised the order Thysanura; both orders possess three-pronged tails comprising two lateral cerci and a medial epiproct or ''appendix dorsalis''. Of the three organs, the appendix dorsalis is considerably longer than the two cerci; in this the Archaeognatha differ from the Zygentoma, in which the three organs are subequal in length. In the late 20th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
