Various grasses, including Bromus sp. (Chiasson, 1986).

identification
At one time C. falsus was believed to constitute a complex of 3 different species, however this species was differentiated from C. simplex and C. patruelis by Zur Strassen's (1960) paper on the genus Chirothrips. See Zur Strassen's (1960) paper for further details on the genus Chirothrips, and C. falsus, C. simplex, and C. patruelis, in particular. Body varies around 1.5mm in length and is dark brown, with orange sub-integumental pigment in the thorax. Head is barely prolonged beyond eyes (Stannard, 1968). Males have 6 ante-ocellar setae (Zur Strassen, 1960). Antennal segment 1 is small, segment 2 is slightly pronounced at the outer angle and the tip is broadly rounded. Thorax lacks stout setae, and the mesoscutum has striae that are not scalloped. Males are brachypterous. Abdominal tergites lack scallops, and abdominal sternites have transverse striae (Stannard, 1968).
