Cymothoe caenis, the common glider, is a species of butterfly of the family Nymphalidae. It is found in Guinea, Sierra Leone, Liberia, Ivory Coast, Ghana, Togo, southern Nigeria, Cameroon, the Republic of the Congo, the Central African Republic, Angola, the Democratic Republic of the Congo, Uganda, Tanzania and Zambia. The habitat consists of forests and heavy woodland. It is a migratory species.
Polypedilum is a genus of non-biting midges in the subfamily Chironominae of the bloodworm family Chironomidae. This is probably the most species-rich of all chironomid genera. Larvae of Polypedilum may also be among the most abundant invertebrates in euthrophic ponds, reaching densities of up to 1200 larvae per square meter.
Stictochironomus is a genus of non-biting midges in the subfamily Chironominae of the bloodworm family Chironomidae. Members of this genus often have strongly marked wings and legs. The larvae of these midges may also have distinct dark patterns on the dorsal side of the head capsule. They live in sand and other sediments in a variety of fresh water habitats in densities of several hundred per square meter.
Caenis amica is a species of mayfly in the genus Caenis. It has an average lifespan of a few days like most mayflies and lives near rivers in the Americas.
Cymothoe is a genus of butterflies in the subfamily Limenitidinae, the admirals and relatives. They are known commonly as gliders. The genus is distributed in the Afrotropical realm, where species are found mainly in forest habitat. mainly in the Guinean Forests of West Africa and the Congolian forests.
In the 10th edition of Systema Naturae, Carl Linnaeus classified the arthropods, including insects, arachnids and crustaceans, among his class "Insecta". Insects with net-veined wings were brought together under the name Neuroptera.
The Course of Honour is a historical novel by Lindsey Davis, set in ancient Rome and concerning the emperor Vespasian and his lover Caenis. It was the first novel Davis wrote which was set in ancient Rome, but was not published until 1997 after she had become known for the Falco series. Davis has said "I see it as my first real book, and because the true story is so wonderful, it will always be my favourite."
Milocera horaria is a species of moth of the family Geometridae first described by Charles Swinhoe in 1904. It is found on Madagascar.
Castellaniella caeni is a Gram-negative, oxidase-positive, catalase-negative, facultatively anaerobic, denitrifying, nonmotile bacterium from the genus Castellaniella, isolated from the sludge of the aerobic treatment tanks of a municipal leachate treatment plant in Daejeon in the Republic of Korea.
Azonexus caeni is a species of nitrogen-fixing bacteria. It is a root bacteria and together with Azonexus fungiphilus and Azonexus hydrophilus is one of the three species in the genus. It is Gram-negative, motile, non-spore-forming and slightly curved rod-shaped. Slu-05T is the type strain.
Sphingobacterium caeni is a Gram-negative, non-spore-forming, rod-shaped and non-motile bacterium from the genus of Sphingobacterium which has been isolated from activated sludge.
Caenis diminuta is a species of small squaregilled mayfly in the family Caenidae. It is found in Central America and North America.
Caenis latipennis is a species of small squaregilled mayfly in the family Caenidae. It is found in Central America, North America. In North America its range includes all of Canada, all of Mexico, and the continental United States.
Chelatococcus caeni is a Gram-negative, non-spore-forming, rod-shaped and motile bacterium from the genus of Chelatococcus which has been isolated from biofilm reactor sludge in Korea.
Flavobacterium caeni is a Gram-negative, heterotrophic, non-spore-forming, aerobic and non-motile bacterium from the genus of Flavobacterium which has been isolated from activated sludge from a sequencing batch reactor.
