Flowers of Indian Pipe (Monotropa sp.) & Obolaria virginica (Nakahara 1994).
Body varies around 1.5mm in length, and is dark brown. The antennae are brown except for the base of segment 3, which is yellow, and the extreme base of segment 4 which is pale (Nakahara 1994). The pedicels of the intermediate antennal segments are yellowish brown and the tibiae and tarsi range from yellowish brown to yellow. The forewings are brown and are paler at the base. The head is moderate in size. Antennae are 7 segmented and antennal segment 3 is stout. Antennal segment 6 is approximately the same size or longer than segment 3. The prothorax is setose, though there are bare areas posteriorly on either side of the midline. On the posterior margins of the prothorax, there are 2 or 3 pairs of setae between the major pairs of setae (Stannard 1968). There are 3 apical setae set on the fore vein of each forewing. Females and males are macropterous, though males are currently only known from 1 specimen (Nakahara 1994). There are 3 setae present on each lateral margin of tergite 2 (Stannard 1968). Pleurotergite 2 has anterolateral setae present (Nakahara 1994). A complete comb of setae is present on the posterior margin of tergite 8 (Stannard 1968), and tergite 9 has 2 pairs of campaniform sensilla (Nakahara 1994).
