The giraffe weevil is sexually dimorphic, with the neck of the male typically being 2 to 3 times the length of that of the female. The total body length of the males is just under 2.5 cm. Most of the body is black with distinctive red elytra covering the flying wings. They can use this extended neck to fight for the right to mate with a female. Female weevil uses her smaller neck to roll a leaf tube, into which a single egg is layed.
