Adult

 
      The adult weevil is a reddish brown cylinder with a long prominent curved snout. It varies considerably in size and is about 35 mm in length and 12 mm in width. The head and rostrum comprise about one third of the total length.

The mouth parts are elongated in the form of a slender snout or rostrum, which bears a small pair of biting jaws at the end and a pair of antennae near the base. The rostrum is reddish brown dorsally, and ventrally it is dark brown. In the male the dorsal apical half of the snout is covered with a pad of short brownish hairs; the snout of the female is bare, more slender, curved and a little longer. The antennae consist of the scape and funicle. The eyes are black and separated on both sides of the base of the rostrum.

The pronotum is reddish brown in color and has a few black spots. These black spots are variable in shape, size and number.

The elytra are dark red, strongly ribbed longitudinally, and do not cover the abdomen completely. The wings are brown in color and the weevils are capable of strong flight.

The male weevil has a tuft of soft reddish brown hairs along the dorsal aspect of the snout; it is absent in the female.
