Polydrusus cervinus
Polydrusus weevils are very similar to the Phyllobius group, but the main difference between the two is that the antennal insertions are on the side of the rostrum and not visible from above. Polydrusus cervinus is a rather pale golden green weevil when fresh but appears blacker as scales become detached.
The tooth on the front femur helps to distinguish P. cervinus from some other species in the genus. P. pilosus is very similar but much scarcer and usually found in north.
