Stephanitis lauri

Laurel lace bug

Description

Stephanitis lauri is a lace bug species from the family Tingidae, specialized in feeding on the leaves of Laurus nobilis. It was first discovered in Crete in 2012 and described in 2014. Since then, it has spread to France, Italy, Spain, Portugal and some other countries, where it is considered an introduced and possibly invasive species. The insect lives on the underside of the leaves, where both nymphs and adults feed by sucking plant sap. This leads to the formation of characteristic discoloration, reducing the aesthetic value of host plants. In severe infestations, defoliation and reduced vigor of the plants may occur. The species thrives mainly in anthropogenic environments such as gardens, parks, and botanical collections, indicating its potential for further spread in Mediterranean regions.

Symptom

On affected leaves, there are numerous small, pale or yellowish spots caused by sap-sucking. The undersides of the leaves may contain dark excrement and shed exoskeletons of the lace bugs. Severely infested leaves may be white or silver-gray in color, dry out and drop prematurely.
