The eggs are pearly white, oblong, and equally rounded at both ends. The larvae are yellowish-white, cylindrical and legless grubs with a reddish brown head. The pupae, about the same size as the adults, are shiny white at first, darkening while maturing, with well-developed wings and legs. Adult weevils are rusty red to grey-brown, have long snouts and cylindrical and posteriorly tapered bodies about 6 mm long. They have ridged and roughened wings with patches of lighter brown or grey scales (Gebeyehu & Wingfield 2003).
