The species appears to be rarely collected or reported, with no observations recorded in iNaturalist as of the available data.

Identification
Distinguished from other Asilidae by the combination of: extremely slender body form, long thin legs, and small relative to body size. Within Leptogaster, separation from requires examination of male terminalia and wing venation details described in Martin (1957). The may be confused with other Leptogastrinae such as Euscelidia or Psilonyx, but Leptogaster species generally have a more gracile build and different wing patterns.
Habitat
Likely associated with grasslands, meadows, or open herbaceous vegetation where Leptogastrinae are commonly found. Members of this typically perch on grass stems and low vegetation to hunt.
Distribution
Original description from an unspecified locality; distribution details require verification from data and subsequent records. The Leptogaster has a broad distribution including North America, Europe, Asia, and Africa.
Behavior
As with other Leptogaster , likely exhibits a distinctive perching on grass stems, waiting in ambush for small flying prey. The slender body form allows hunting in dense vegetation where larger, more robust robber flies cannot maneuver effectively.
Ecological Role
of small Diptera and other minute insects in grassland . Contributes to regulation of of small flying insects in herbaceous .
