Remarks
- Structure: Female scale oyster shaped or mytiliform when fully grown, about 1.75 mm long, 0.75 mm wide; chalk white; exuvia, straw-coloured, at elevated end, partly or entirely covered with white waxy dust which rubs off easily; ventral scale well developed, with dorsal completely enclosing and sealing insects. Male scale same shape, but only about half the size of the female (Kotinsky, 1915). Scale of the female white, broad and elongate, tapering somewhat posteriorly; that of the male white, elongate, and slender (Ferris, 1938a). Colour photograph by Gill (1997).
- Biology: Occurring beneath the sheathing bases of the leaves and on the rootstocks.
- Economic Importance: The Bermuda grass scale, is the most polyphagous species among the Odonaspidinae, was reported to damage lawn grasses in Israel (Halperin, 1971; Berlinger & Barak, 1981) and to be a common pest of forage and turf grasses in the Southern United States (Dale and McCoy, 1964; Tippins & Martin, 1982).
- General Remarks: Description and illustration of adult female by Ferris (1938a), McKenzie (1956), Ben-Dov (1988b), Gill (1997) and by Colon-Ferrer & Medina-Gaud (1998).
