This is the first report of this species from Morrocco. Very few studies exist on its biology. Kazak et al. (2002) showed its ability to develop feeding on T. urticae   . Sengonca & Dresher (2001) studied the ability of this species to develop feeding on Thrips tabaci   (Lindeman) and concluded that this food alters its biological parameters in comparison to T. urticae   .

Specimens examined: 2001, Meknes on unknown plant (1 female); 2003, Gorges of Zegzel on Echium   sp. ( Boraginaceae   ) (2 females), Mentha pulegium   (Limiaceae) (6 females), S partel Cape on Dittrichia viscosa   ( Asteraceae   ) (7 females, 3 males).

Previous records: Armenia, Azerbaijan, Byelorussia, Caucasus region, Denmark, England, France, Georgia, Germany, Hungary, Iran, Italy, Jamaica, Latvia, Mexico, Moldova, Montenegro, Norway, Poland, Russia, Slovakia, Spain, Switzerland, Turkey, Ukraine, USA.
