Stomorhina lunata is a species of fly in the family Rhiniidae first described by Johan Christian Fabricius in 1805.

[4] These distinctive, medium-sized blowflies are rather similar to the house flies, but they have a characteristic prominent proboscis, a longitudinally striped thorax and an abdomen with yellow and black bands.

[5] This distinctively marked species is often misidentified because of the unusual band pattern in the abdomen, typical of hoverflies.

Stomorhina lunata is an important egg predator of some major African agricultural pests, the South African brown locust (Locustana pardalina), the more widespread desert locust (Schistocerca gregaria), and the migratory locust (Locustana migratoria).

They can usually be found feeding on nectar and pollen of umbellifer flowers (Apiaceae) and of Asteraceae species (mainly Scorzoneroides autumnalis, Tanacetum vulgare, Anthriscus sylvestris, Erysimum cheiranthoides, Filipendula ulmaria).
