[2] The western flower thrips, Frankliniella occidentalis, has spread until it now has a worldwide distribution, and is the primary vector of plant diseases caused by tospoviruses. They fly in an unsteady circular motion. The mass occurrence of thrips is a quite annoying phenomena, particularly, if the tiny insects – sometimes attracted by coloured cloth – land on people. [25], Mirothrips arbiter has been found in paper wasp nests in Brazil. [61] When coupled with the increasing globalization of trade and the growth of greenhouse agriculture, thrips, unsurprisingly, are among the fastest growing group of invasive species in the world. The wings rotate around their trailing edges to begin the "fling", creating useful forces. Where do thrips come from?
