Description
Sarcophagidae is the dipteran family commonly known as flesh flies, comprising approximately 2000 species. Many species of Sarcophagidae prefer to breed in carrion over other mediums, but there are several species that breed in dung. A large number of species are parasitoids or cleptoparasitoids and never breed in carrion. It is difficult to identify the S. haemorrhoidalis species unless genitalia can be observed. Only males can be identified and classified within the genus. Sarcophagids are rather large in size ranging from 4 to 16 mm. Distinguishing characteristics include a checkerboard like pattern on the abdomen, stripes on the thorax and red eyes. Flesh flies are attracted to anything rotting, including feces. Sarcophagidae are unimpeded by rain and fly in any weather. Because of this trait, Sarcophagidae will often be the first flies to colonize a corpse after an extended period of rain. Flesh flies appear to prefer sunlight over shaded conditions. Sarcophaga haemorrhoidalis (Bercaea cruentata) is the one of the most common species of Sarcophagidae recovered from indoor crime scenes in the United States.

Famous quotes containing the word description:
“Why does philosophy use concepts and why does faith use symbols if both try to express the same ultimate? The answer, of course, is that the relation to the ultimate is not the same in each case. The philosophical relation is in principle a detached description of the basic structure in which the ultimate manifests itself. The relation of faith is in principle an involved expression of concern about the meaning of the ultimate for the faithful.”
—Paul Tillich (1886–1965)
“The Sage of Toronto ... spent several decades marveling at the numerous freedoms created by a “global village” instantly and effortlessly accessible to all. Villages, unlike towns, have always been ruled by conformism, isolation, petty surveillance, boredom and repetitive malicious gossip about the same families. Which is a precise enough description of the global spectacle’s present vulgarity.”
—Guy Debord (b. 1931)
“To give an accurate description of what has never occurred is not merely the proper occupation of the historian, but the inalienable privilege of any man of parts and culture.”
—Oscar Wilde (1854–1900)
