Sarcophagidae

Definition

A family of calyptrate flies (order Diptera) commonly called flesh flies, characterized by ovoviviparity—females deposit larvae rather than eggs onto carrion, dung, decaying organic matter, or open wounds. Larvae of most species are saprophagous, but some are parasitoids of orthopterans or kleptoparasites of solitary bees and wasps (subfamily Miltogramminae). Adults feed on fluids from carcasses, nectar, and exudates. The family is taxonomically diverse with roughly 3,000 described species and is frequently encountered in forensic entomology, where larval development data help estimate postmortem intervals.

Etymology

From Greek sarko- (flesh) + -phage (eating), with family suffix -idae, referring to larval feeding habits on animal remains.

Example

Forensic entomologists distinguish Sarcophagidae from Calliphoridae (blow flies) at carcass sites by noting that flesh fly larvae are typically deposited as first instars rather than hatching from eggs on the substrate.

Usage Notes

The common name 'flesh fly' is sometimes applied loosely to any fly associated with carrion, but technically refers only to Sarcophagidae. Distinguishing sarcophagid larvae from calliphorid larvae in the field requires examining posterior spiracular slits; sarcophagids have three straight slits in a triangular pattern, while calliphorids have a more sinuous or branched peritreme. The subfamily Miltogramminae is behaviorally divergent, with females depositing larvae at the burrow entrances of solitary bees and wasps rather than on carrion.
