The species epithet 'schaefferi' honors an entomologist, following the common practice of the era.

in the Leptogaster can be distinguished from other Asilidae by their exceptionally slender, elongate bodies and disproportionately long, thin legs. The genus is further characterized by a small , narrow , and elongated . Specific identification of L. schaefferi from requires examination of detailed morphological features including genitalic structures and precise wing venation patterns.
Diet
As with all Asilidae, Leptogaster schaefferi is predatory. The Leptogaster is known to capture small, soft-bodied prey such as aphids, small flies, and other tiny insects, often taken from vegetation rather than in .
Behavior
Leptogaster are typically found in vegetation, where they perch on stems and leaves to ambush prey. Unlike many larger robber flies, they do not typically capture prey in but rather snatch small insects from plant surfaces.
Ecological Role
As a of small insects, Leptogaster schaefferi contributes to natural of of tiny plant-feeding insects such as aphids.
