Ectobius Kirgizius
''Ectobius'' is a genus of non-Cosmopolitan distribution, cosmopolitan cockroaches once thought native to the Old World and described by James Francis Stephens in 1835, belonging to the family Ectobiidae, subfamily Ectobiinae. The discovery of 4 ectobius cockroaches in Colorado dating to 49 million years ago suggests the genus actually originated in North America. This genus has been subject to a number of revisions.Bohn, H. 1989: Revision of the ''sylvestris'' group of ''Ectobius'' Stephens in Europe (Blattaria: Blattellidae). ''Entomologica Scandinavica'', 20: 317–342. Description The adult 'cockroaches' reach of length, the basic coloration of their body is mostly brown or yellowish, with a clearer margin.

Cosmopolitan Distribution
In biogeography, a cosmopolitan distribution is the range of a taxon that extends across most or all of the surface of the Earth, in appropriate habitats; most cosmopolitan species are known to be highly adaptable to a range of climatic and environmental conditions, though this is not always so. Killer whales ( orcas) are among the most well-known cosmopolitan species on the planet, as they maintain several different resident and transient (migratory) populations in every major oceanic body on Earth, from the Arctic Circle to Antarctica and every coastal and open-water region in-between. Such a taxon (usually a species) is said to have a ''cosmopolitan'' distribution, or exhibit cosmopolitanism, as a species; another example, the rock dove (commonly referred to as a ' pigeon'), in addition to having been bred domestically for centuries, now occurs in most urban areas around the world. The extreme opposite of a cosmopolitan species is an endemic (native) species, or one foun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
