Calyptoproctus elegans is a species of planthopper in the family Fulgoridae. It is found from Brazil north to Honduras.
Dauer describes an alternative developmental stage of nematode worms, particularly rhabditids including Caenorhabditis elegans, whereby the larva goes into a type of stasis and can survive harsh conditions. Since the entrance of the dauer stage is dependent on environmental cues, it represents a classic and well studied example of polyphenism. The dauer state is given other names in the various types of nematodes such as ‘diapause’ or ‘hypobiosis’, but since the C. elegans nematode has become the most studied nematode, the term ‘dauer stage’ or 'dauer larvae' is becoming universally recognised when referring to this state in other free-living nematodes. The dauer stage is also considered to be equivalent to the infective stage of parasitic nematode larvae.
The Auchenorrhyncha suborder of the Hemiptera contains most of the familiar members of what was called the "Homoptera" – groups such as cicadas, leafhoppers, treehoppers, planthoppers, and spittlebugs. The aphids and scale insects are the other well-known "Homoptera", and they are in the suborder Sternorrhyncha.
A planthopper is any insect in the infraorder Fulgoromorpha, in the suborder Auchenorrhyncha, a group exceeding 12,500 described species worldwide. The name comes from their remarkable resemblance to leaves and other plants of their environment and that they often "hop" for quick transportation in a similar way to that of grasshoppers. However, planthoppers generally walk very slowly. Distributed worldwide, all members of this group are plant-feeders, though few are considered pests. The infraorder contains only a single superfamily, Fulgoroidea. Fulgoroids are most reliably distinguished from the other Auchenorrhyncha by two features; the bifurcate ("Y"-shaped) anal vein in the forewing, and the thickened, three-segmented antennae, with a generally round or egg-shaped second segment (pedicel) that bears a fine filamentous arista.
Ceratodus is an extinct genus of lungfish. It has been described as a "catch all", and a "form genus" used to refer to the remains of a variety of lungfish belonging to the extinct family Ceratodontidae. Fossil evidence dates back to the Early Triassic. A wide range of fossil species from different time periods have been found around the world in places such as the United States, Argentina, Greenland, England, Germany, Egypt, Madagascar, China, and Australia. Ceratodus is believed to have become extinct sometime around the beginning of the Eocene Epoch.
Derbidae is a family of insects in the order Hemiptera, the true bugs. It is one of the largest and most diverse families of planthoppers. It is widely distributed around the world, especially in the tropics, and with many species in subtropical and temperate regions.
Dictyopharidae is a family of planthoppers, related to the Fulgoridae. The family comprises nearly 760 species in more than 150 genera which are grouped into two subfamilies, Dictyopharinae and Orgeriinae.
Metcalfa pruinosa, the citrus flatid planthopper, is a species of insect in the Flatidae family of planthoppers first described by Thomas Say in 1830.
Issus is a genus of planthoppers belonging to the family Issidae of infraorder Fulgoromorpha of suborder Auchenorrhyncha of order Hemiptera. Like most members of the order Hemiptera they live on phloem sap that they extract with their piercing, sucking mouth parts.
F. elegans may refer to:
Calyptoproctus is a genus of planthoppers in the family Fulgoridae and the type genus of subtribe Calyptoproctina; records are from central and south America.
Catenipora is an extinct genus of tabulate corals in the family Halysitidae, known from the Ordovician to the Silurian.
Douvillinella is an extinct genus of prehistoric brachiopods in the extinct family Douvillinidae. Species are from the Devonian of the Czech Republic and Germany. C. elegans is found only at Arauz Formation, Lezna Member, Palencia Province, North Spain.
Cyclopteris is an extinct genus of seed ferns in the extinct family †Cyclopteridaceae. Species are from the Carboniferous.
Kosswigianella is a genus of delphacid planthoppers in the family Delphacidae. There are about 10 described species in Kosswigianella. Some authorities have placed AcanthodelphaxLe Quesne, 1964 here as a subgenus, but this is disputed.
Delphacinae is a subfamily of delphacid planthoppers in the family Delphacidae. There are at least 1,700 described species in Delphacinae.
Metadelphax is a genus of delphacid planthoppers in the family Delphacidae. There are at least 5 described species in Metadelphax.
Tropiduchidae is a family of planthoppers in the order Hemiptera. There are at least 160 genera and 600 described species in Tropiduchidae.
Achilidae is a family of planthoppers, sometimes called "achilids" in the order Hemiptera. There are at least 520 described species in Achilidae.
Fulgoridiidae are an extinct family of Mesozoic planthoppers. They are the earliest group of planthoppers known, and appear to be a paraphyletic assemblage ancestral to living planthoppers. The majority of known members of the family lived in the Jurassic period, though the group also includes one Cretaceous taxon. All currently known species are from Eurasia.
Florissantia is an extinct monotypic genus of planthopper in the dictyopharid subfamily Dictyopharinae. The single species, Florissantia elegans, was described by Samuel Hubbard Scudder (1890) from fossils found in the Florissant Formation of Colorado.
