Many species of the Dexinæ are of the most metallic-green or blue. They are principally found in Australia.
The Flesh Fly (Sarcophaga carnaria) belongs to the Sarcophaginæ and is one of our largest species. The larvæ of some species are called "Screw Worms" in America.
The fourth sub-family, the Muscinæ, contains the most typical species of the Diptera or two-winged flies. The common House Fly (Musca domestica) is the most familiar example. Several blue-and-green flies are produced from larvæ which feed on more or less putrid flesh, and are well known to anglers as "Gentles." The Blow Fly or Blue Bottle (Musca vomitoria) is one of these, also the Green Bottle Fly (Lucilia Cæsar) which is often common about hedges in the summer time. Many species belong to the sub-family Anthomyiinæ, are very small insects, and their larvæ mine in the leaves of plants like those of Tineæ.
