One of many similar green bugs found on various deciduous trees during summer.  Length approximately 6 mm. The brown tibial spines arise from black spots and the 2nd antennal segment is longer than the width of the pronotum at the base.   The clavus is partly or entirely darkened and it usually has two dark marks above the cuneus.  Some individuals are less clearly marked.   Males are easier to identfy than females, with a narrow vertex and large eyes.  Associated with a range of deciduous tree species, especially lime

Nymphs of this species cannot be identifed with confidence.

Orthops campestris can look very similar, but has much shorter antennae and is smaller 

Detailed examination of the specimen is needed to identify the species.

Found on a range of deciduous trees, in particular Lime.
