Plants like sunflowers, cocklebur, and ragweed are attractive to Cocklebur Weevils. Each long red and black weevil has a black oval-shaped spot on the middle of its pronotum and several black dots on the wing coverings. The amount of black on the lower half of the wing coverings varies with some individuals showing a large blob, while others look like they were dipped in black ink. All have the trademark 'snout' or 'nose' on the face that is common with most weevils. This type of beetle uses that long rostrum to chew into plants. Their feeding habit leaves plant stems with dry patches, but they seem insignificant to plant health when only a few are present. Cocklebur Weevils prefer to remain unseen and hide in curled leaves and behind stems and flowers when they perceive they are being watched.
