Description

Pachytodes cerambyciformis can reach a length of 7–12 mm. These beetles have a quite compact body. Elytra are only about twice as long as broad, and clearly narrower towards the end. Head, pronotum and legs are black. Elitra are matt, light brownish-yellow, with black markings, which are very variable and sometimes absent. Usually they show two transversal black bands and a black apex. The first band usually is not continuous, while the second black band is narrower in the center. The suture is normally light brownish-yellow. This species is very similar to Pachytodes erraticus. The differences are listed in the below table.
