Common NameEastern Flower Thrips (Stannard, 1968)
SeasonalityMay to July (Webb et al., 1970).
IdentificationThe body is yellow, and has dark setae. Antennal segments 6 to 8 and the distal half of segment 4 are brown, and the forewing is pale. The head is wider than long. The antennae are 8 segmented, and segments 3 and 4 each have a forked sense cone. Antennal segment 3 is slightly swollen at the pedicel, and segment 8 is no longer than 7. Three pairs of ocellar setae are present, and pair 3 arises along the anterior margins of the ocellar triangle. The pronotum has 5 pairs of major setae, and the anteromarginal setae are shorter than the anteroangulars. The metanotum has 2 pairs of setae along the anterior margin, and a pair of campaniform sensilla. This species is macropterous, and each forewing has 2 complete rows of veinal setae. Tergites 5 to 8 each have a pair of lateral ctenidia, and the posteromarginal comb on tergite 8 has only a few teeth. Sternites 3 to 7 lack discal setae (Moritz et al., 2001).
