Ricania Speculum
''Ricania speculum'', common name Black planthopper or Ricaniid Planthopper, is a species of planthoppers belonging to the family Ricaniidae. This species is considered a major agricultural pest for several crops in tropical and subtropical areas (apples, coffee plants, oil palms, Citrus species, etc.). Distribution and habitat This species is widespread in China, India, Indonesia, Japan, Korea, Philippines and Vietnam. Recently, it has been accidentally introduced in northern Italy, possibly with ornamental plants or crops. This species can be found in the low-elevation mountains and prefers dark environments. Description ''Ricania speculum'' can reach a length of about , with a wingspan of about . These planthoppers have dark brown wings with central wavy horizontal bands and irregular transparent patches of different sizes. The precostal area of the forewings shows dense transverse veinlets and the costal margin is distinctly convex near the base.Cui-Ping Bu and Ai-Ping Lian ...

Francis Walker (entomologist)
Francis Walker (31 July 1809 – 5 October 1874) was an English entomologist. He was born in Southgate, London, on 31 July 1809 and died at Wanstead, England on 5 October 1874. He was one of the most prolific authors in entomology, and stirred controversy during his later life as his publications resulted in a huge number of junior synonyms. However, his assiduous work on the collections of the British Museum had great significance. Between June 1848 and late 1873 Walker was contracted by John Edward Gray Director of the British Museum to catalogue their insects (except Coleoptera) that is Orthoptera, Neuroptera, Hemiptera, Diptera, Lepidoptera and Hymenoptera. Walker largely accomplished this and (Edwards, 1870) wrote of the plan and by implication those who implemented it “It is to him raythat the Public owe the admirable helps to the study of natural history which have been afforded by the series of inventories, guides, and nomenclatures, the publication of which beg ...

Ricaniidae
Ricaniidae is a family of planthopper insects, containing over 400 species worldwide. The highest diversity is in tropical Africa and Asia and in Australia, with a few species occurring in the Palearctic and Neotropical realms.

Citrus
''Citrus'' is a genus of flowering plant, flowering trees and shrubs in the rue family, Rutaceae. Plants in the genus produce citrus fruits, including important crops such as Orange (fruit), oranges, Lemon, lemons, grapefruits, pomelos, and lime (fruit), limes. The genus ''Citrus'' is native to South Asia, East Asia, Southeast Asia, Melanesia, and Australia (continent), Australia. Various citrus species have been used and domesticated by indigenous cultures in these areas since ancient times. From there its cultivation spread into Micronesia and Polynesia by the Austronesian expansion (c. 3000–1500 BCE); and to the Middle East and the Mediterranean (c. 1200 BCE) via the incense trade route, and onwards to Europe and the Americas. History Citrus plants are native to subtropical and tropical regions of Asia, Island Southeast Asia, Near Oceania, and northeastern Australia. Domestication of citrus species involved much hybridization and introgression, leaving much uncertainty ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hemiptera Of Asia
Hemiptera (; ) is an order (biology), order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, Reduviidae, assassin bugs, Cimex, bed bugs, and shield bugs. They range in size from to around , and share a common arrangement of piercing-sucking Insect mouthparts, mouthparts. The name "true bugs" is often limited to the suborder Heteroptera. Entomologists reserve the term ''bug'' for Hemiptera or Heteroptera,Gilbert Waldbauer. ''The Handy Bug Answer Book.''
