Imago body size S. oryzae when out of the pupa± 2.16 mm, the full development of ± 3.36 mm, and S. zeamais when out of the pupa± 2.54 mm, ± 4.78 at fuH development. Imago S. oryzae bright black or brownish black, has four round spot elongated (oval) on the elytra are reddish brown and reddish brown legs, while the imago S. zeamais solid black/dark colored -Mth four spots on the elytra yellowish brown and yellowish brown leds.
