|scientific name Baliothrips |
Grasses, and sedges (Chiasson, 1986).
Adults collected in June, July, and August.
The head is of moderate size and slightly wider than long. Ocelli are present and are close together in a triangle. Interocellar and postocular setae are small. The antennae are seven segmented, with segments 3 and 4 each having a forked sense cone, and the maxillary palps are 2 segmented. The epimeral setae on the prothorax are well developed with 3 pairs of setae located along the posterior margin of the prothorax between the pairs of epimeral setae. The mesospinasternum and metasternum are separated by a suture and the metascutum is longitudinally striate. The tarsi are 2 segmented. Each fore wing has 2 longitudinal veins, with interrupted setae on the fore vein while the hind vein is evenly covered with setae. The abdominal sternites lack accessory setae, but most have a posterior pair of setae forward of the margin (Stannard, 1968).
