A smallish green weevil about 5 mm in length, sometimes called the Small Green Nettle Weevil. Most Phyllobius weevils have a prominent tooth on the underside of the femora, but this is not the case with Phyllobius roboretanus. It also has a very steep, almost vertical, rear end to the elytra. It has round scales and dark femora.
This species is quite similar to P. virideaeris, which is another Phyllobius without the femoral tooth (the third is P. viridicollis but this lacks scales and appears black), but they differ on the underside. P. roboretanus only has a thin covering of fine scales, with much of the underlying surface visible. In P. virideaeris the underside is densely coated with round scales, the same as the upperside. P. roboretanus also appears rather earlier in the year. However the easiest way to separate them is by the steepness of the elytra at the posterior end - this is very steep in P. roboretanus but shallow in P. virideaeris.
