This species has not been studied by the present authors, but is similar in structure to F. tritici.
F. insignis is very similar to, and is possibly the Western USA form of, the Eastern flower thrips, F. tritici. Currently 230 species are listed in the genus Frankliniella, with up to 130 further names placed into synonymy (Nakahara, 1997). This high rate of synonymy has been due to unrecognized variability in size and color of so many species. Scarcely ten of these species are native to parts of the world other than the Americas.
