Acraea Trimeni
''Acraea trimeni'' or Trimen's acraea is a butterfly of the family Nymphalidae. It is found in only in the arid savannah in the northern Northern Cape and the western part of the Free State. The wingspan is 43–49 mm for males and 45–55 mm for females. Adults are usually on wing from October to March with a peak in late October. There might be two or continuous generations per year. Taxonomy The status of this species is uncertain. ''Acraea trimeni'' was described as a form or aberration of ''Acraea barberi''. Aurivillius (1898) is uncertain as to whether ''trimeni'' is an aberration or variety of ''barberi'' Trimen. Eltringham (1912) retains the rank of aberration of ''barberi'' Trimen. Van Son (1963) considers ''trimeni'' as a subspecies of ''zetes''. In his phylogenetic analysis of 1992–1993, Henning considers the Aurivillius description as a good species, but ''trimeni'' may be a synonym of ''barberi''. Eltringham's text reads "In the example named ab. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Butterflies Described In 1899
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the Order (biology), order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily (zoology), superfamily Papilionoidea, which contains at least one former group, the skippers (formerly the superfamily "Hesperioidea"), and the most recent analyses suggest it also contains the moth-butterflies (formerly the superfamily "Hedyloidea"). Butterfly fossils date to the Paleocene, about 56 million years ago. Butterflies have a four-stage life cycle, as like most insects they undergo Holometabolism, complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN Red List Least Concern Species
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roland Trimen
Roland Trimen Fellow of the Royal Society, FRS (29 October 1840 in London – 25 July 1916 in London) was a British-South African Natural history, naturalist, best known for ''South African Butterflies'' (1887–89), a collaborative work with Colonel James Henry Bowker. He was among the first entomologists to investigate mimicry and Polymorphism (biology), polymorphism in butterflies and their restriction to females. He also collaborated with Charles Darwin to study the pollination of ''Disa (plant), Disa'' orchids. Life and career Trimen was born in London in 1840, the son of Richard and Mary Ann Esther Trimen and the older brother of the botanist Henry Trimen (1843-1896) who went to Ceylon (now Sri Lanka). He went to study at Rottingdean and then at King's College School in Wimbledon. Trimen was interested in entomology but a chronic Larynx, laryngeal condition forced him to move to the Cape of Good Hope as a treatment. Reaching there he volunteered under Edgar Leopold ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

Acraea (butterfly)
''Acraea'' is a genus of brush-footed butterflies (family Nymphalidae) of the subfamily Heliconiinae. It seems to be highly paraphyletic and has long been used as a "wastebin taxon" to unite about 220 species of anatomically conservative Acraeini. Some phylogenetic studies show that the genus ''Acraea'' is monophyletic if ''Bematistes'' and Neotropical ''Actinote'' are included (see Pierre & Bernaud, 2009). Most species assembled here are restricted to the Afrotropical realm, but some are found in India, Southeast Asia, and Australia.Silva-Brandão et al. (2008) Biology The eggs are laid in masses; the larvae are rather short, of almost equal thickness throughout, and possessing branched spines on each segment, young larvae group together on a protecting mass of silk; the pupa is slender, with a long abdomen, rather wide and angulated about the insertion of the wings, and suspended by the tail only. '' A. horta'', '' A. cabira'', and '' A. terpsicore'' illustrate typical life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phylogenetic
In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An unrooted tree diagram (a network) makes no assumption about the ancestral line, and does ...
