Stigmella Intermedia
''Stigmella intermedia'' is a moth of the family Nepticulidae. It is found in North America in Ohio, Arkansas, Kentucky and Ontario. The wingspan is 3-3.5 mm. Usually there are two generations per year, with larvae maturing in July and overwintering, but occasionally a third generation appears. The larvae feed on '' Rhus typhina'' and '' Rhus aromatica''. They mine the leaves of their host plant. The loosened epidermis is bright green at first, later yellowish, and is marked by a broad blackish frass Frass refers loosely to the more or less solid excreta of insects, and to certain other related matter. Definition and etymology ''Frass'' is an informal term and accordingly it is variously used and variously defined. It is derived from the G ... line nearly as broad as the mine. The larvae are very bright green. External linksNepticulidae of North America [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Annette Frances Braun
Annette Frances Braun (1884–1978) was an American entomologist and leading authority on microlepidoptera, a grouping of mostly small and nocturnal moths. Her special interest was leaf miners: moths whose larvae live and feed from within a leaf. Early life and education Annette Frances Braun was born on August 24, 1884, to George F. and Emma Maria (Wright) Braun in Cincinnati, Ohio. She got her education at the University of Cincinnati, receiving her A.B. in 1906, her A.M. in 1908, and her Ph.D. in 1911, making her the first woman to earn a Ph.D. from the University of Cincinnati; her younger sister Emma Lucy Braun would be the second. Career Braun began her career as a zoology teaching assistant at the University of Cincinnati (1911–19) before turning to private research. She developed expertise in the moths of the eastern North American forests, becoming an international authority who has been described as one of the most accomplished lepidopterists of the 20th century.

Moth
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.

Nepticulidae
Nepticulidae is a family of very small moths with a worldwide distribution. They are characterised by eyecaps over the eyes (see also Opostegidae, Bucculatricidae, Lyonetiidae). These pigmy moths or midget moths, as they are commonly known, include the smallest of all living moths, with a wingspan that can be as little as 3 mm in the case of the European pigmy sorrel moth, but more usually 3.5–10 mm. The wings of adult moths are narrow and lanceolate, sometimes with metallic markings, and with the venation very simplified compared to most other moths. The minute larvae usually are leaf miners but some species also mine seeds or bark of trees. Much is known about their host plants. The Pectinivalvinae, characterised by a "pectinifer" on the valve of the male genitalia, are endemic to Australia, where they mine the leaves of the tree families Myrtaceae (Scoble, 1983) or Cunoniaceae ( Eucryphiaceae), and Elaeocarpaceae (Hoare, 2000). This Australian group probably cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wingspan
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the other wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingspan of , the official record for a living bird. The term wingspan, more technically extent, is also used for other winged animals such as pterosaurs, bats, insects, etc., and other aircraft such as ornithopters. In humans, the term wingspan also refers to the arm span, which is distance between the length from one end of an individual's arms (measured at the fingertips) to the other when raised parallel to the ground at shoulder height at a 90º angle. Former professional basketball player Manute Bol stood at and owned one of the largest wingspans at .

Rhus Typhina
''Rhus typhina'', the staghorn sumac, is a species of flowering plant in the family Anacardiaceae, native to eastern North America. It is primarily found in southeastern Canada, the northeastern and midwestern United States, and the Appalachian Mountains, but it is widely cultivated as an ornamental throughout the temperate world. Etymology The specific epithet ''typhina'' is explained in Carl Linnaeus and Ericus Torner's description of the plant with the phrase "Ramis hirtis uti typhi cervini", meaning "the branches are rough like antlers in velvet". In both French and German, the common name of the species (''sumac vinaigrier; Essigbaum'') means "vinegar tree". Description ''Rhus typhina'' is a dioecious, deciduous shrub or small tree growing up to tall by broad. It has alternate, pinnately compound leaves long, each with 9–31 serrate leaflets long. Leaf petioles and stems are densely covered in rust-colored hairs. The velvety texture and the forking pattern of the bran ...

Rhus Aromatica
''Rhus aromatica'', the fragrant sumac, is a deciduous shrub in the family Anacardiaceae native to North America.(1) (2) It is found in southern Canada (Alberta to Quebec) and nearly all of the lower 48 states except peninsular Florida. Fragrant sumac is a woody plant with a rounded form that grows to around to tall and to wide. The plant develops yellow flowers in clusters on short lateral shoots in March through May. The flower is a small, dense inflorescence that usually opens before the plant's leaves do. The species is polygamodioecious (mostly dioecious, primarily bearing flowers of only one sex, but with either a few flowers of the opposite sex or a few bisexual flowers on the same plant). Male (staminate) flowers develop in yellowish catkins, while female (pistillate) flowers develop in short bright yellow panicles at the ends of branches. Pollinated flowers develop clusters of to hairy red drupes containing a single nutlet during June through August. The fru ...

Mine The Leaves
A leaf miner is any one of numerous species of insects in which the larval stage lives in, and eats, the leaf tissue of plants. The vast majority of leaf-mining insects are moths ( Lepidoptera), sawflies (Symphyta, the mother clade of wasps), and flies ( Diptera). Some beetles also exhibit this behavior. Like woodboring beetles, leaf miners are protected from many predators and plant defenses by feeding within the tissues of the leaves, selectively eating only the layers that have the least amount of cellulose. When attacking ''Quercus robur'' (English oak), they also selectively feed on tissues containing lower levels of tannin, a deterrent chemical produced in great abundance by the tree. The pattern of the feeding tunnel and the layer of the leaf being mined is often diagnostic of the insect responsible, sometimes even to species level. The mine often contains frass, or droppings, and the pattern of frass deposition, mine shape, and host plant identity are useful to dete ...
