The Figwort Weevil (Cionus scrophulariaehas) is a member of family Curculionidae. They are about 4-5mm long (male smaller then female) and having hairy brownish body with black spots and a gray colored head and thorax. There are two large velvety black spots on the wing-cases, where the cases meet. They feed on the plants in Figwort family. I found this mating pair on mullein plant.
