This study was carried out to determine distribution, host plant and biology of Ricania simulans (Walker) (Hemiptera: Ricaniidae) in Eastern Black Sea Region of Turkey between 2009 and 2011. There is no important plant pest in the Eastern Black Sea Region of Turkey except this species. However, population of R. simulans being harmful in many wild and cultivated plant species in both nymphal and adult stages has been increased since 2009.
