Biology. Sarcophaga praedatrix, also referred to as Sarcophaga tryoni Johnston and Tiegs 1921, is a common species throughout Australia. In Brisbane, larvae are not believed to survive the cooler months between June and August (Johnston & Tiegs 1921). Sarcophaga praedatrix has been caught at decayed-carrion baits by KAM and has also been recorded by JFW in forensic cases in Australia.

Note that data on praedatrix in the literature may include the undescribed species listed here as ‘ Sarcophaga (Sarcorohdendorfia) sp_A sp. nov. (unnamed species near praedatrix)’.

Taxonomy. The larval instars were described by Cantrell (1981; referred to as Tricholioproctia tryoni). DNA barcode sequences of S. praedatrix have been deposited in both GenBank and BOLD.
