Sloth Moth
A sloth moth is a coprophagous moth which has evolved to exclusively inhabit the fur of sloths and to use sloth dung as a substrate for the early stages of reproduction. Sloth moths include '' Bradypodicola hahneli'', ''Cryptoses choloepi'', ''Cryptoses waagei'', ''Cryptoses rufipictus'', and ''Bradypophila garbei''. Certain lepidopteran moths of the snout moth family Pyralidae (namely subfamily Chrysauginae) have evolved to inhabit sloth fur exclusively. Typically, sloth moths follow a life-style broadly on the lines of ''Cryptoses choloepi'', a moth in the snout moth family that lives exclusively in the fur of the brown three-toed sloth '' Bradypus variegatus infuscatus''. Adult female moths leave the fur of the sloth to lay eggs in the sloth droppings when the sloth descends, once a week, to the forest floor to defecate. The larvae of ''Cryptoses choloepi'' live in the dung and newly emerged moths later fly from the dung pile into the forest canopy to find a host sloth. Chrysau ...

Bradypophila Garbei
''Bradypophila'' is a genus of snout moths. It was described by R. v. Ihering in 1914, and contains the species ''Bradypophila garbei''. It is found in Brazil Brazil ( pt, Brasil; ), officially the Federative Republic of Brazil (Portuguese: ), is the largest country in both South America and Latin America. At and with over 217 million people, Brazil is the world's fifth-largest country by area .... The forewings are unicolorous dark ochreous. The larvae are associated with tree sloths.

Chrysauginae
The Chrysauginae are a subfamily of snout moths ( family Pyralidae). They are primarily Neotropical and include about 400 described species. Description and ecology The subfamily includes the sloth moths (genera ''Cryptoses'', ''Bradypodicola'' and ''Bradypophila''). The caterpillar larvae of these species feed on the dung of sloths, and adults live in the sloths' fur. Other unusual Chrysauginae caterpillars have been found in Hymenoptera nests and on the spines of caterpillars of the brush-footed butterfly genus ''Automeris''. But usually, their larvae feed on plants, boring into seed, fruits, stems and roots, or rolling and spinning leaves together to form a hideout. While the adults are fairly nondescript, Chrysauginae larvae can usually be recognized unequivocally by the sclerotised ring around seta SD1 of the metathorax. Systematics In 1995, Solis et al. compiled a checklist of Chrysauginae for the Western Hemisphere. However, phylogenetic analyses have not been conduc ...

Moths Of South America
Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. Differences between butterflies and moths While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.Scoble, MJ 1995. The Lepidoptera: Form, function and diversity. Oxford, UK: Oxford University Press; 404 p. Although the rules for distinguishing moths from butterflies are not well establishe ...

Pyraloidea
The Pyraloidea (pyraloid moths or snout moths) are a moth superfamily containing about 16,000 described species worldwide, and probably at least as many more remain to be described. They are generally fairly small moths, and as such, they have been traditionally associated with the paraphyletic Microlepidoptera. This superfamily used to contain the Hyblaeidae, Thyrididae, Alucitidae (plus Tineodidae), Pterophoridae, and Pyralidae. The first four families are now each split off as a distinct superfamily. Nowadays, Pyralidae are usually split into the Pyralidae sensu stricto and the Crambidae, as both groups have been shown to be monophyletic and a sister group. Some genera (e.g. '' Micronix'' and '' Tanaobela'') still defy easy classification and have been variously assigned to the Crambidae or the Pyralidae. Among all Lepidoptera, pyraloids show the most diverse life history adaptations. The larvae of most species feed on living plants either internally or externally as ...

Arthropods Associated With Sloths
A large number of arthropods are associated with sloths. These include biting and blood-sucking flies such as mosquitoes and sandflies, triatomine bugs, lice, ticks and mites. The sloth’s fur forms a micro-ecozone inhabited by green algae and hundreds of insects. Sloths have a highly specific community of commensal beetles, mites and moths. Species of sloths recorded to host arthropods include: * Pale-throated three-toed sloth ''Bradypus tridactylus'' * Brown three-toed sloth ''Bradypus variegatus'' * Linnaeus's two-toed sloth '' Choloepus didactylus'' The large variety of arthropods associated with sloths comprise two distinct feeding guilds – the haematophagous guild, represented by biting flies, mites, and ticks, and the coprophagous guild which comprises a unique assemblage of moths and beetles which utilize the sloth principally for phoresis and whose larval stages feed and develop in the dung of the host sloth. Haematophagous guild Six species of ticks of the genus ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

9 (nine) is the natural number following and preceding . Evolution of the Arabic digit In the beginning, various Indians wrote a digit 9 similar in shape to the modern closing question mark without the bottom dot. The Kshatrapa, Andhra and Gupta started curving the bottom vertical line coming up with a -look-alike. The Nagari continued the bottom stroke to make a circle and enclose the 3-look-alike, in much the same way that the sign @ encircles a lowercase ''a''. As time went on, the enclosing circle became bigger and its line continued beyond the circle downwards, as the 3-look-alike became smaller. Soon, all that was left of the 3-look-alike was a squiggle. The Arabs simply connected that squiggle to the downward stroke at the middle and subsequent European change was purely cosmetic. While the shape of the glyph for the digit 9 has an ascender in most modern typefaces, in typefaces with text figures the character usually has a descender, as, for example, in . The mod ...
