Family: Curculionidae
Subfamily: Conoderinae
Length: 2.5-3.0 mm
Members of this subfamily are notable for their large, close-set eyes, and for a beak that is tucked away into a channel on the ventral side.
In Cylindrocopturus, the elytra are modestly wider than the pronotum; antennomere 3 is shorter than 2; and the femora arent toothed.
As the scientific name suggests, adult Cylindrocopturus quercus are found on oaks. Downie and Arnett (1996) report that the species breeds in Ragweed.
