Pyrrhocoridae
Pyrrhocoridae is a family of insects with more than 300 species world-wide. Many are red coloured and are known as red bugs and some species are called cotton stainers because their feeding activities leave an indelible yellow-brownish stain on cotton crops. A common species in parts of Europe is the firebug, and its genus name ''Pyrrhocoris'' and the family name are derived from the Greek roots for fire "pyrrho-" and bug "coris". Members of this family are often confused with, but can be quickly separated from, Lygaeidae by the lack of ocelli (simple eyes) on the top of the head. Description The membrane of the forewing has one or two cells from which about 7-8 branching veins emerge that may have branches that fuse together ( anastomose) while the main veins reach the margins of the wing. They have three tarsal segments. They can be very difficult to separate from some members of the family Largidae, which also share some of these characters and belong to the same super famil ...

Dysdercus Suturellus
''Dysdercus suturellus'' is a species of true bug in the family Pyrrhocoridae, commonly known as a cotton stainer. The adult insect is slender, about long, with a red thorax and dark brown wings marked with a yellow cross. It is native to the southeast of the United States, Jamaica and Puerto Rico. It is a pest of cotton crops and other plants, the adults and older nymphs feeding on the emerging bolls and the ripening seeds. Description The adult ''Dysdercus suturellus'' is about long. It has a red head with black antennae, the first segment of which are longer than the second. The thorax has a white pronotal collar and is otherwise mostly red. The sternites of the abdomen are red, bordered with white posteriorly. The corium, the leathery base of the wings, is dark brown margined with cream, giving the insect a large cross-shaped pattern. Distribution and hosts ''Dysdercus suturellus'' is native to the southeasternmost part of the United States, Jamaica and Puerto Rico. It is ...

Melamphaus Faber
''Melamphaus'' is an Old World genus of true bugs in the family Pyrrhocoridae, the cotton stainers. They are often confused with bugs in the family Lygaeidae, but can be distinguished by the lack of ocelli on the head. The genus has adults with large and characteristic oval shape and the body is densely covered in short hair. The head behind the eye narrows slightly and the eyes are at a distance from the fore edge of the pronotum. The edge of the pronotum is not extended to the sides or bent down. The metathoracic scent gland has an ostiole with a peritreme and a deep furrow. The sutures on the underside of the abdominal segments between 4 and 5; and between 5 and 6 are strongly curved forwards. Many species may swarm seasonally on seeds of specific trees. ''Melamphaus faber'' is known to be found in large numbers on ''Hydnocarpus anthelmetica'' and ''H. wightiana'' in Singapore. Species that have been included in the genus include: * ''Melamphaus agnatus'' Bergroth, 1894 * '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrrhocoris Apterus
The firebug, ''Pyrrhocoris apterus'', is a common insect of the family Pyrrhocoridae. Easily recognizable due to its striking red and black coloration, it may be confused with the similarly coloured though unrelated '' Corizus hyoscyami'' (cinnamon bug or squash bug). ''Pyrrhocoris apterus'' is distributed throughout the Palaearctic from the Atlantic coast of Europe to northwest China. It has also been reported from the United States, Central America, and India, and is also found in Australia. It has been reported as recently expanding its distribution northwards into mainland United Kingdom and eastward on to the coast of the Mediterranean Sea. They are frequently observed to form aggregations, especially as immature forms, containing from tens to perhaps a hundred individuals. Reproduction Firebugs generally mate in April and May. Their diet consists primarily of seeds from lime trees and mallows ( see below). They can often be found in groups near the base of lime tree tr ...

Antilochus (genus)
''Antilochus'' is an Old World genus of true bugs in the family Pyrrhocoridae. The genus currently contains about 25 species, occurring in tropical Africa including Madagascar, South and Southeast Asia, the Malay Archipelago, and New Guinea. ''Antilochus'' are brightly coloured, usually red and black, and easily differentiated from other pyrrhocorids by the head being transversely depressed behind the eyes. They are often confused with bugs in the family Lygaeidae, but can be distinguished by the lack of ocelli A simple eye (sometimes called a pigment pit) refers to a form of eye or an optical arrangement composed of a single lens and without an elaborate retina such as occurs in most vertebrates.

Dysdercus Cingulatus, Mating
''Dysdercus'' is a widespread genus of true bugs in the family Pyrrhocoridae; a number of species attacking cotton bolls may be called "cotton stainers". Description Species may be confused with bugs in the family Lygaeidae, but can be distinguished by the lack of ocelli on the head. They can be readily distinguished from most other genera of Pyrrhocoridae by the strong white markings at the junction of the head and thorax, and along the sides of the thorax, and often abdomen. Species ''BioLib'' lists the following: ; subgenus ''Dysdercus'' Guérin-Méneville, 1831 * '' Dysdercus andreae'' (Linnaeus, 1758) * ''Dysdercus bimaculatus'' (Stål, 1854) * ''Dysdercus cardinalis'' Gerstäcker, 1873 * ''Dysdercus concinnus'' Stål, 1861 * ''Dysdercus fasciatus'' Signoret, 1861 - cotton stainer (Africa) * ''Dysdercus mimulus'' Hussey, 1929 * '' Dysdercus mimus'' (Say, 1832) * ''Dysdercus nigrofasciatus'' Stål, 1855 * '' Dysdercus obliquus'' (Herrich-Schaeffer, 1843) * '' Dysdercus ob ...

Dysdercus Cingulatus
''Dysdercus cingulatus'' is a species of true bug in the family Pyrrhocoridae, commonly known as the red cotton stainer. It is a serious pest of cotton crops, the adults and older nymphs feeding on the emerging bolls and the cotton seeds as they mature, transmitting cotton-staining fungi as they do so. Description ''Dysdercus cingulatus'' grows to a length of . It is mainly red but has a white collar and three black spots. It is closely related and very similar to ''Dysdercus koenigii'' but ''D. cingulatus'' is slightly larger and the femora have varying amounts of black while ''D. koenigii'' has completely red femora. Distribution ''D. cingulatus'' occurs in Nepal, Sri Lanka, northeastern India, Bangladesh, Thailand, the Philippines, Sumatra, Borneo, Papua New Guinea, Argentina, and northern Australia.

Antilochus Coquebertii
''Antilochus coquebertii'' (often misspelled as ''coqueberti'') is an Old World species of true bug in the family Pyrrhocoridae, occurring in South and Southeast Asia.

Aeschines (genus)
Aeschines (; Greek: , ''Aischínēs''; 389314 BC) was a Greek statesman and one of the ten Attic orators. Biography Although it is known he was born in Athens, the records regarding his parentage and early life are conflicting; but it seems probable that his parents, though poor, were respectable. Aeschines' father was Atrometus, an elementary school teacher of letters. His mother Glaukothea assisted in the religious rites of initiation for the poor. After assisting his father in his school, he tried his hand at acting with indifferent success, served with distinction in the army, and held several clerkships, amongst them the office of clerk to the '' Boule.''

Berry, London, 1905) Among the campaigns that Aeschines participated in were Phlius in the Peloponnese (368 BC), Battle of Mantinea (362 BC), and Phokion's campaign in Euboea (349 BC). T ...
