General Description

Body varies from 1mm to 1.3mm in length, and is generally dark brown, with legs lighter in colour than the rest of the body, and forewings are a light grayish brown. Orange subintegumental pigment present in thorax and abdomen. Males are somewhat more yellowish and have brownish patches on the thorax and abdominal segments 1 and 2. The head is moderate in size, but not prolonged in front of the eyes. Interocellar setae are long relative to the post ocular setae. The sides of the pedicel are straight on antennal segment 3. Ocelli are present, but are reduced in brachypters. Major setae on the prothorax are moderately long with the inner anterior pair of setae smaller or about the same size as the dorsal length of the compound eye. Both sexes occur in macropterous and micropterous forms. An interrupted comb of setae is present along the posterior margin of abdominal tergite 8. Males have single, transverse, elipsoid glandular areas present on abdominal sternites 3 to 7 (Stannard, 1968).
