The oviposition, eggs, emergence of first instar larvae, and larvae of Mallophora orcina (Wiedemann, 1828) are described and compared with those of Mallophora spp., Megaphorus spp., and other species of robber flies. Oviposition occurred on vegetation 1–3 m above the ground with approximately 188–323 eggs deposited in layers in a chalky-white albumin. The eggs are elongate and initially glistening white. They turn a dark metallic color on the end where larvae emerge from. Upon emergence the larvae drop to the ground where they bury themselves in the soil. Larvae are shiny white, dorsoventrally flattened, tapering at each end, with a distinct head, 3 thoracic segments, and 9 abdominal segments. The separation between most segments is not visible or clearly delineated.
