Length 5.5 to 7.0 mm. Lygocoris species can be distinguished from similar green bugs by the very fine and inconspicuous pale brown tibial spines and at high magnification, the break in the keel between the eyes. The pronotum is rather straight-sided. In L. rugicollis the pronotum is strongly wrinkled and the entire upper surface lacks obvious hairs. The side margins are often yellow. There are other very similar species and care needs to be taken with identification.

Nymphs of this species cannot be identifed with confidence.

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

Found on various Salix species.

Adult: May to October.

Widely scattered throughout Britain.

Occasional in Leicestershire and Rutland.
