SeasonalityAdults collected in June and August.IdentificationThe head is small, and somewhat prolonged behind the eyes. Ocelli are present in females, and absent (as far as is known) in males. Antennae are 8 segmented, with segment 1 enlarged, segment 2 is usually produced at the outer apex, and the last 2 segments forming a style. Antennal segment 3 has simple sense cones and segment 4 has forked or simple sense cones. Prothorax is large, trapezoidal, forelegs are enlarged, and tarsi are 2 segmented. Females are macropterous, and males are apterous or brachypterous. Forewings with 2 veins, setae on both veins are interrupted (Stannard, 1968).

Members of this genus breed in the flowers of Gramineae, with each individual thrips developing in a single floret. The varying nutritional values of each floret are believed to produce individuals of various sizes, which may have resulted in multiple names for some species of thrips in this genus (Mound and Marullo, 1996).
