Identification
Members of the Systena are small leaf beetles, typically 3–5 mm in length, with enlarged hind adapted for jumping—a characteristic trait of flea beetles (tribe Alticini). Systena bitaeniata can be distinguished from by the presence of two pale longitudinal stripes on the dark , as indicated by the epithet "bitaeniata" (meaning "two-banded"). Specific diagnostic features separating this species from other Systena species require examination of genitalia or other subtle morphological characters.

Data Limitations
Detailed biological information for S. bitaeniata specifically is sparse in the accessible literature. Most ecological and behavioral knowledge of the derives from studies of economically significant such as S. blanda, and direct transfer of these traits to S. bitaeniata is not warranted without confirmation.
