Remarks

• Structure: Adult female brown, yellowish brown to dark brown, mealybug-like. The gravid female secretes a mass of shiny fluffy wax threads at posterior end of abdomen. The apex of the abdomen of the adult female becomes gradually invaginated as eggs are laid. (Kondo, et al., 2022)
• Biology: The female lays an average of 167 eggs in a wax sac. At the same time the apex of her abdomen is retracted into the body until a deeply invaginated cavity is formed to hold the developing eggs. The incubation period varies from 12 to 23 days. (Gavrilov-Zimin, 2018)
• Economic Importance: In Arizona, USA, this species was reported to cause twig blight and 'flagging' of ponderosa pine, Pinus ponderosa. (McKenzie et al., 1948)
• General Remarks: Description and illustration of adult female by Morrison (1939) and by McKenzie (1943a, 1943b).
