vegetable weevils
Listroderes is a genus of weevils in the family Curculionidae, subfamily Cyclominae. The genus includes at least 170 described species, though some sources suggest a smaller core group. Several species, particularly Listroderes costirostris (vegetable weevil), are significant agricultural pests with broad host ranges. The genus is characterized by distinctive body vestiture of subcircular to suboval scales. Species are native to southern South America, with some introduced widely through human activity.
