DESCRIPTION

Thrips are tiny, 2-3 mm (less than 1/8 inch) in length, slender insects with long fringes on the margins of their wings. Thrips undergo incomplete metamorphosis, have multiple generations per year, and can be phytophagous or predaceous. Sixspotted thrips adults can be distinguished from other species by the three dark spots on each wing cover of the mostly pale-yellow adult. Nymphs are translucent white to yellow and difficult to discern from other thrips species. Adults and larvae are entirely predaceous, feeding most commonly on mites such as the European red mite, cyclamen mite, and Tetranychus spp. spider mites. Sixspotted thrips can rapidly reduce high mite populations, but often don't become numerous until after mites have become abundant and damaging.
