Over all length 8 - 9mm. In spring, when they are mating, they are pale green but when the new generation matures in July they are straw-coloured. The pronotum has a longitudinal groove and the femora have no spurs. The pronotum is coarsely and densely pitted. There are two other very similar Stenodema species and the female of Notostira elongata is also a confusion species.
