The genus Polydrusus and Phyllobius include weevils that look alike, but the frontlegs of the Polydrusus species are smooth; those of the Phyllobius species have a little spike that points backwards.
In addition, Phyllobius species have antennae that grow from the top of the snout; Polydrusus species have antennae that grow from the side of snout (clearly visible on the photo's).
