Length 3.5 to 4.5 mm. The four UK species of this genus are distinguished by the presence of a forewing appendix. This is a membranous area at the tip of the wing which is not crossed by any veins. Identification is difficult due to species similarity and the existence of different colour forms. Dark spots can usually be seen at the base of the tibial spines in this species.
On Pedunculate Oak (Quercus robur). Adults may also be found on other deciduous trees.
Adult: June to October
