Fishfly
Fishflies are members of the subfamily Chauliodinae, belonging to the megalopteran family Corydalidae. They are most easily distinguished from their closest relatives, dobsonflies, by the jaws (mandibles) and antennae. In contrast to the large jaws (especially in males) of dobsonflies, fishfly mandibles are not particularly noticeable or distinctive, and the males have feathery antennae similar to many large moths. '' Chauliodes pectinicornis'', the "summer fishfly", is a well-known species in North America. Fishflies lay their eggs upon vegetation overhanging streams, whence the larvae, as soon as hatched, drop into the water, and go about preying upon aquatic animals. When ready to transform to pupae, they crawl out upon the bank and are then found in cavities under stones or even under the bark of trees. Fishflies are quite large, with a wingspan of . They will eat aquatic plants as well as small animals including vertebrates like minnows and tadpoles, and may live up to sev ...

Chauliodes Pectinicornis
''Chauliodes pectinicornis'' known as Summer fishfly, is a species of fishfly from North America. Distribution ''C. pectinicornis'' has a wide distribution in the eastern Canada and United States, from Maine in the north-east to Alachua, Liberty and Santa Rosa counties in Florida to the south-east, and as far west as Kansas. Taxonomic history ''C. pectinicornis'' was first described by Carl Linnaeus in his 1763 work '' Centuria Insectorum''. Synonyms: Linnaeus 1763 ''Hemerobius pectinicornis, Hemerobius virginiensis, Semblis pectinicornis, Chauliodes virginiensis.'' Ecology ''C. pectinicornis'' has a commensal relationship with ''Plecoptcracoluthus downesi'' larvae, which undergo their entire life cycle including pupation on the fishfly's mesothorax The mesothorax is the middle of the three segments of the thorax of hexapods, and bears the second pair of legs. Its principal sclerites (exoskeletal plates) are the mesonotum (dorsal), the mesosternum (ventral), and the mesop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Megaloptera
Megaloptera is an order of insects. It contains the alderflies, dobsonflies and fishflies, and there are about 300 known species. The order's name comes from Ancient Greek, from ''mega-'' (μέγα-) "large" + ''pteryx'' (πτέρυξ) "wing", in reference to the large, clumsy wings of these insects. Megaloptera are relatively unknown insects across much of their range, due to the adults' short lives, the aquatic larvae's often-high tolerance of pollution (so they are not often encountered by swimmers etc.), and the generally crepuscular or nocturnal habits. However, in the Americas the dobsonflies are rather well known, as their males have tusk-like mandibles. These, while formidable in appearance, are relatively harmless to humans and other animals; much like a peacock's feathers, they serve mainly to impress females. However, the mandibles are also used to hold females during mating, and some male dobsonflies spar with each other in courtship displays, trying to flip each ...

Corydalidae
The family Corydalidae contains the megalopterous insects known as dobsonflies and fishflies. Making up about one dozen genera,See references in Haaramo (2008) they occur primarily throughout the Northern Hemisphere, both temperate and tropical, and South America. They are sizeable Megaloptera, with a body usually larger than 25 mm (1 inch). They often have long filamentous antennae, though in male fishflies they are characteristically feathered. Ocelli are present; the fourth tarsal segment is cylinder-shaped. The four large wings are translucent, smoky grey, or mixed, and the anterior pair is slightly longer than the posterior one. Their aquatic larvae are used as fish bait and are called hellgrammites. The eastern dobsonfly, ''Corydalus cornutus'', is the most well-known North American species among the dobsonflies. These genera have distinctive elongated mandibles in males and form the subfamily Corydalinae. The genera in which the males have normal mandibles, called ...

Dobsonfly
Dobsonflies are a subfamily of insects, Corydalinae, part of the Megalopteran family (biology), family Corydalidae. The larvae (commonly called hellgrammites) are aquatic insect, aquatic, living in streams, and the adults are often found along streams as well. The nine genera of dobsonflies are distributed in the Americas, Asia, and South Africa. Etymology The origin of the word "dobsonfly" is unclear. John Henry Comstock used the term in reference to these insects in his 1897 book ''Insect Life'', but did not explain it. He also mentioned that angling, anglers used the word "hellgrammite" for the aquatic larvae they used as bait, but the origin of this term is also unknown. Description Adult dobsonflies are some of the largest non-Lepidopteran insects of temperate zones such as the United States and Canada, with a wingspan of up to in some species of ''Corydalus''.Stange, Lionel.

Moth
Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. Differences between butterflies and moths While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.Scoble, MJ 1995.

Pupa
A pupa ( la, pupa, "doll"; plural: ''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 and precedes adulthood (''imago'') in insects with complete metamorphosi ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Vertebrate
Vertebrates () comprise all animal taxa within the subphylum Vertebrata () ( chordates with backbones), including all mammals, birds, reptiles, amphibians, and fish. Vertebrates represent the overwhelming majority of the phylum Chordata, with currently about 69,963 species described. Vertebrates comprise such groups as the following: * jawless fish, which include hagfish and lampreys * jawed vertebrates, which include: ** cartilaginous fish (sharks, rays, and ratfish) ** bony vertebrates, which include: *** ray-fins (the majority of living bony fish) *** lobe-fins, which include: **** coelacanths and lungfish **** tetrapods (limbed vertebrates) Extant vertebrates range in size from the frog species ''Paedophryne amauensis'', at as little as , to the blue whale, at up to . Vertebrates make up less than five percent of all described animal species; the rest are invertebrates, which lack vertebral columns. The vertebrates traditionally include the hagfish, which do no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
