Generally brown or dark grey, though females exhibit more colour variation than males and are frequently lighter coloured (recently emerged adults may be green). The abdominal intersegment colour is yellow-green, and the thorax is paler chestnut with dark bands. Forewing membrane without distinct pattern but apical cells have faint brown patches and small darker patches at the margin of cells cu, m and m, forewing veins mid-brown with dark spots at the apices where the 1 1 2 veins intersect the wing margin. Description. Loginova (1976). Nymph Colour. Fifth pale grey-green or blue green with black tergites; terminal antennal segment darker brown. Fifth instar measurements: (Specimens 7) BL: 1.6–1.9; BW: 1.08–1.23; WL: 0.57–0.6; CPL: 0.48–0.54; CPW: 0.7–0.76; RW: 0.16–0.17; HW: 0.66–0.77; AL: 0.93–1.02. Fifth instar chaetotaxy. Head setae simple and narrowly capitate; antennal setae simple; ocular seta simple, dark, conspicuous; primary and secondary post-ocular setae distinctly capitate. Dorsal thoracic setae short simple and long capitate. Forewing pad macrosetae 9–14, distinctly capitate, surface and marginal (typically two to four surface setae with the remainder marginal); hindwing pad macrosetae five or six, distinctly capitate, surface and marginal; proximal setae distinctly capitate; simple microsetae scattered on the wing pad surfaces. Dorsal abdominal pre-caudal macrosetae present on anterior tergites, long capitate, caudal plate macrosetae, six, distinctly capitate; sectasetae absent; marginal abdominal setae (other than sectasetae) four pairs, distinctly capitate; pleurite setae paired capitate and simple. Legs with capitate setae present on femora and tibiae; foreleg with two capitate setae on tibia (one proximal, one distal); middle leg capitate setae on tibia four or five; hind leg capitate setae on tibia five or six.
