Sphaeroceroidea
Sphaeroceroidea is a superfamily of flies. It includes the cosmopolitan families of Sphaeroceridae (small dung flies), Heleomyzidae, and Chyromyidae, as well as a few smaller groups. It has about 2,600 species. Description Sphaeroceroids tend to be small flies a few millimetres in length. Each of the families has its own distinguishing traits. For example, Sphaeroceridae have black wings with an interrupted costa, and the first tarsomere of the hind leg is short and thick. Nannodastiidae are even smaller than usual for sphaeroceroids, with adults being 0.70-1.25 mm long, and their legs lack long setae. Ecology Larvae generally live and feed in various kinds of decaying organic matter, including manure, seaweed, fungi, rotting wood, compost and carrion. Nannodastiidae have a more restricted lifestyle. Adults have usually been found in tropical and subtropical beaches, often in caves or under cliff overhangs. The larvae are unknown, but they may be in the droppings of birds a ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Sphaeroceridae
Sphaeroceridae are a family of true flies in the order Diptera, often called small dung flies, lesser dung flies or lesser corpse flies due to their saprophagous habits. They belong to the typical fly suborder Brachycera as can be seen by their short antennae, and more precisely they are members of the section Schizophora. There are over 1,300 species and about 125 genera accepted as valid today, but new taxa are still being described. Unlike the large "corpse flies" or blow-flies of the family Calliphoridae and the large dung flies of the family Scathophagidae, the small dung flies are members of the schizophoran subsection Acalyptratae. Among their superfamily Sphaeroceroidea, they seem to be particularly close relatives of the family Heleomyzidae. Description and ecology Dung flies are small to minute, usually dull-colored flies with characteristically thickened first tarsomere of the posterior leg. The first tarsal segment is less than times as long as the sec ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Heleomyzidae
The Heleomyzidae is a small family of true flies in the insect order Diptera. Over 740 described species of Heleomyzidae occur in about 76 generaPape, Thomas, Vladimir Blagoderov, and Michail B. Mostovski. "Order Diptera Linnaeus, 1758." Animal Biodiversity. Magnolia Press, 2011. distributed throughout the world. Description Heleomyzids are small to medium-sized flies which vary in colour from yellow to reddish yellow or reddish brown to black. The wings often have small but distinctly longer, well-spaced spines mixed with the shorter spines along the leading edge and the crossveins are often clouded. Taxonomy Over 740 described species of Heleomyzidae occur in about 76 genera and 22 tribes distributed throughout the world; the greatest number occur in the Holarctic region. Around 100 species of Heleomyzidae are found in North America. Most of the subfamilies have been commonly recognized as families in the past, but are now included within the Heleomyzidae.

Taxonomic Rank
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family (biology), family, order (biology), order, class (biology), class, phylum (biology), phylum, kingdom (biology), kingdom, domain (biology), domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of phenotypic trait, traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to iden ...

Seta
In biology, setae (singular seta ; from the Latin word for "bristle") are any of a number of different bristle- or hair-like structures on living organisms. Animal setae Protostomes Annelid setae are stiff bristles present on the body. They help, for example, earthworms to attach to the surface and prevent backsliding during peristaltic motion. These hairs make it difficult to pull a worm straight from the ground. Setae in oligochaetes (a group including earthworms) are largely composed of chitin. They are classified according to the limb to which they are attached; for instance, notosetae are attached to notopodia; neurosetae to neuropodia. Crustaceans have mechano- and chemosensory setae. Setae are especially present on the mouthparts of crustaceans and can also be found on grooming limbs. In some cases, setae are modified into scale like structures. Setae on the legs of krill and other small crustaceans help them to gather phytoplankton. It captures them and allows th ...

Manure
Manure is organic matter that is used as organic fertilizer in agriculture. Most manure consists of animal feces; other sources include compost and green manure. Manures contribute to the fertility of soil by adding organic matter and nutrients, such as nitrogen, that are utilised by bacteria, fungi and other organisms in the soil. Higher organisms then feed on the fungi and bacteria in a chain of life that comprises the soil food web. History According to a Byzantine tradition attributed to Cassianus Bassus pig dung was generally not usable as fertilizer, except for almond trees. Similar views recorded by Columella were unrelated to the Islamic taboos of later centuries, though the medieval Andalusian writer Ibn Bassal and some later writers from Yemen also recorded negative effects of pig dung "burning" plants. Ibn Bassal described a sort of mixed manure with straw or sweeping mixed in as ', implying that was not composed of only manure. The sweepings from hot baths inc ...

Chyromyidae
Chyromyidae are small to very small cyclorrhaphous, acalypterate flies ( Diptera) currently classified within the Heleomyzoidea by most authors. The majority have a pale yellow integument and bright iridescent green, red or purple eyes. The family is represented in all continents except Antarctica. There are about 150 named species in this family worldwide. There has been no comprehensive taxonomic study to elucidate the generic limits of species in the family. Currently, only four genera are recognised, but ongoing studies of the African species indicate that there are more. Biology The biology of Chyromyidae is poorly known and no life history of any species has been elucidated. Adults are xerophilic and have been collected on flowering plant Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to tho ...

Fungus
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true f ...

Wood
Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or woodchips or fiber. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the productio ...
