Adults are 5.3 - 7.4 mm in length, narrow bodied and much paler in color than any other species of the genus Amara. Brown to reddish brown with pale bronze luster. Appendages brownish yellowish and almost transparent. Eyes are convex. Basal half of prothorax is parallel sided with truncated anterior margin, more or less denticulate hind angles. It also has expanded punctuation (having tiny spots, punctures) at the base which is a key character. Prosternum of male is smooth. Elytra are long with shallow striations and with punctuation. Male genitalia smaller, straight and long apex and lateral lobes with hooks (Lindroth, 1968).

Adults are predatory on other arthropod species and are omnivorous. Predation on cabbage root fly maggots has been noted (Andersen et al., 1983; Varis et al.1984). Adults are also found to feed on weed seed of Taraxacum officinale (Dandlion) seed (Honek et al., 2005).
