Biology. In Korea, this species was collected from wild roses ( Rosaceae ) such as Rosa multiflora Thunb. , Rosa rugosa Thunb. , and Rosa davurica Pall , and was commonly attracted to light. During field surveys and laboratory observations nymphs and adults together were found feeding on the aphid Sitobion ibarae (Matsmura 1917) ( Fig. 1 View FIGURE 1 A–B).
