|scientific name Aptinothrips |
Grass leaves and leaf sheathes (Palmer, 1975).
Nymphs or adults can be found throughout spring and early summer in North America (Bailey, 1957).
Body is long, slender, and mainly yellow. Head is longer than wide and ocelli are absent (Mound and Marullo, 1996). Antennae are 6 to 8 segmented, with simple sense cones on segments 3 and 4 (Stannard, 1968). Maxillary palps are 3 segmented, and the prothorax is moderately setose (Stannard, 1968). Prosternal ferna is divided (Mound and Marullo, 1996). Legs are short and tarsi are 1 or 2 segmented. Males and females of all species in this genus are apterous (Stannard, 1968). The abdomen is long and slender, and both tergites and sternites lack craspeda, though sternites have discal setae. Male tergite 9 has 2 pairs of thorn-like setae (Mound and Marullo, 1996).
Species in this genus feed and breed in the leaf sheaths of grasses (Mound et al., 1976). Members of this genus can also be mistaken for the larval forms of other species due to their pale colour, and apterous condition (Chiasson, 1986). Species in this genus are found on grass leaves or in leaf sheathes in temperate regions of the world (Palmer, 1975).
There are 4 species in this genus, 2 of which occur in Alberta (Mound et al., 1976).
Members of this genus feed on the developing leaves of grasses within the leaf sheathes.
Members of this genus are holarctic (Mound et al., 1976).
