Information: - The Brachyceran infraorder Muscomorpha is a large and diverse group of flies, containing the bulk of the Brachycera, and, most of the known flies. It includes a number of the most familiar flies, such as the housefly, the fruit fly, and the blow fly. The antennae are short, usually three-segmented, with a dorsal arista. Their bodies are often highly setose, and the pattern of setae is often taxonomically important. - The Brachycera are a suborder of the order Diptera. It is a major suborder consisting of around 120 families. Their most distinguishing characteristic is reduced antenna segmentation. A summary of the main physiological characteristics is: - The soldier flies ( Stratiomyidae , sometimes misspelled as Stratiomyiidae , from Greek - soldier ; - fly ) are a family of flies ( historically placed in the now - obsolete group Orthorrhapha ) . The family contains over 2,700 species in over 380 extant genera worldwide . Adults are found near larval habitats , which are found in a wide array of locations , mostly in wetlands , damp places in soil , sod , under bark , in animal excrement and in decaying organic matter . They are diverse in size and shape , though they commonly are partly or wholly metallic green , or somewhat wasplike mimics , marked with black and yellow or green and sometimes metallic . They are often rather inactive flies which typically rest with their wings placed one above the other over the abdomen . - Orthorrhapha is a circumscriptional name which historically was used for an infraorder of Brachycera, one of the two suborders into which the order Diptera, the flies, are divided. As the group was paraphyletic, it has not been used in classifications in the last decade, and is effectively obsolete. However, many catalogs, checklists, and older works still contain the name. The taxa that used to be in the Orthorrhapha now comprise all of the infraorders in Brachycera excluding the Muscomorpha (= "Cyclorrhapha"). - In biological classification, circumscriptional names are taxon names that are not ruled by ICZN and are defined by the particular set of members included. Circumscriptional names are used mainly for taxa above family-group level (e. g. order or class), but can be also used for taxa of any ranks, as well as for rank-less taxa. What is the relationship between 'stratiomyidae' and 'taxon'?
