The first apparent nectarivorous weevil, Smicronyx squalidus, is documented on Desmanthus illinoensis. Although found feeding from extra-floral nectaries (EFN’s) located between the petioles of D. illinoensis, it is believed that S. squalidus merely supplements its diet with nectar, due to an apparent lack of mouthpart modifications for a more efficient uptake of fluids. Photographs of the adult S. squalidus, as well as the EFN’s on D. illinoensis, are provided.
