The Almond Lace Bug, Monosteira unicostata (Mulsant & Rey, 1852) (Hemiptera, Tingidae), a new bug for the Alsace fauna (north-eastern France)

Abstract  ̶  The true bug Monosteira unicostata (Mulsant & Rey, 1852) (Hemiptera, Tingidae), also called the Almond Lace Bug, is a bug that can cause damage to fruit trees (Rosaceae). However, this bug feeds mainly on Salicaceae and Betulaceae in France. Monosteira unicostata is here reported for the first time in north-eastern France in the Grand Est and Alsace regions. Several hundred imagos and larvae were found in a ruderal area exclusively on young Populus alba L., 1753 in Lauterbourg (Haut-Rhin department). The Almond Lace Bug appears to be expanding towards the north of Europe, as well as throughout the world. Its presence in Germany is therefore highly probable.
