Biology. Sarcophaga littoralis has been collected at ocean beaches ( Johnston & Tiegs 1922) and documented to have emerged from the common purple snail, Janthina janthina (ANIC collections). This species has also been collected at decayed-carrion baits by KAM.

Taxonomy. This species belongs to the monotypic subgenus Hardyella. DNA barcode sequences of S. littoralis have been deposited in both GenBank and BOLD.
