|scientific name Odontothrips |
Fields of mixed vegetation, on legumes (Mound et al., 1976).
Adults collected in June and July.
The body varies in length from 1.3 to 2.0 mm, with females larger than males. The body is brown to almost black, with antennal segments 3, and usually part of 4 yellow (Pitkin, 1972). The head is medium in size and ocelli are present. Antennae are 8 segmented, and segments 7 and 8 form a style. Both antennal segments 3 and 4 each have a forked sense cone (Stannard, 1968). The sense cone on segment 6 is usually enlarged. Three pairs of ocellar setae are present, and pair 3 arises within or on the anterior margins of the ocellar triangle. The pronotum has 2 elongate pairs of posteroangular setae. The metanotum has 2 pairs of setae near or on the anterior margin (Pitkin, 1972). A wide suture separates the mesospinasternum and the metasternum. Each foretibia has one or two claw-like processes on the apex. Both sexes of all adult members of this genus are macropterous. Each fore wing has two veins; the setae on the fore vein are interrupted sub-apically. Pleural plates are present on the abdomen, and males lack abdominal glandular areas (Stannard, 1968).
The members of this genus breed in the flowers of Leguminosae (Rapiliouseae) (Mound et al., 1976).
All species in this genus cause some damage to flowers, O. confusus is a pest (Pitkin, 1972).
