Aleochara lustrica
Aleochara lustrica is a rove beetle (Staphylinidae) with a dual life history: adults are predatory on fly larvae, while larvae are ectoparasitoids of cyclorrhaphan fly pupae. The species has been documented across the Americas from Canada to southern Brazil, with recent records extending its known range. It has confirmed associations with sarcophagid flies under laboratory conditions and plays a role in regulating populations of necrophagous Diptera of medical, veterinary, and forensic importance.
Sarcophagidae
flesh flies, satellite flies
Sarcophagidae is a large family of calyptrate flies in the order Diptera, commonly known as flesh flies due to the necrophagous habits of many species. The family comprises approximately 2,842 species worldwide, with peak diversity in the Neotropics. Unlike most flies, sarcophagids are larviparous, depositing live first-instar larvae rather than eggs onto carrion, dung, decaying organic matter, or open wounds. The family includes three subfamilies with diverse life histories: Sarcophaginae (necrophagous, saprophagous, and parasitoid species), Miltogramminae (kleptoparasitic), and Paramacronychiinae (predatory or parasitoid). Species such as Wohlfahrtia magnifica and Sarcophaga haemorrhoidalis cause traumatic myiasis in livestock and humans. Due to their early colonization of carcasses, sarcophagids are important forensic indicators for postmortem interval estimation.
