All life stages occur throughout the year (Mound et al., 1976).
The body varies around 1.5mm in length, and antennal segments 4 and 5 and the sides of the tibiae are brownish. Antennal segment 6 and the end of the abdomen are a dark brown. The head is somewhat reticulate in the anterior two thirds, but is transversely striate in the posterior third (Stannard, 1968). Antennae are 6-segmented (Mound and Marullo, 1996). Antennal segment 2 does not have flanged sides, and segment 6 is large and consists of morphological segments 6 to 8. Tarsi are 1 segmented. Abdominal tergite 9 has short posterior setae (Stannard, 1968).
Often abundant in pastures but there is little evidence of crop damage (Mound and Kibby, 1998).
