The blow flies are a metallic blue or green color and are ubiquitous in nature.  The antennae are aristate with a plumose bristle, and the calypters are large and prominent.  They are distinguished by the absence of a post-scutellum.  These scavenger insects lay their eggs on dead animals.  The larvae feed on decaying tissue of animals.  They are efficient disease vectors of dysentery.
