The Japanese flower thrips, Thrips setosus, originates from Japan and Korea and was recently introduced into Europe. It was found in a Hydrangea nursery in the Netherlands in 2014 and has since then also been reported from several other European countries. Currently, it is a pest of greenhouse grown Hydrangea in the Netherlands and other European countries. In Japan, it has reportedly affected a wide range of host plants but not Hydrangea.
