Remarks

• Systematics: Subfamily: Eulecaniinae (Choi & Lee, 2019) For details about the date of publication of the type species, see De Lotto (1971)
• Structure: See colour photograph in Kawai (1980, Figs. 6.55, a,b). The differences in wax glands and wax secretion between females and males reflect their different needs for living habitats and different ecological strategies. Sciophilous male nymphs are with five types of wax glands, and the wax glands on the dorsum secrete a layer of wax filaments plausibly for protection against direct light irradiation. On the other hand, five types of wax glands were found on the abdomen of females. Heliophilous female nymphs hardly secrete any wax, but the wax glands located along the spiracle on the abdomen may help this insect to breathe. Female adults secrete wax filaments on eggs to protect them from predators and prevent themselves from sticking to each other. Males appear to secrete wax for creating a shaded niche that fits their sciophilous life style, whereas females are likely to adopt an ecological strategy with thickened epidermis for heliophilous acclimatization and overwintering. (Qi, et al., 2019)
• Biology: A biparental species, which develops one annual generation in Japan (Kuwana, 1923b), Russia, Vladivostok region (Danzig, 1965, 1967, 1980b) and in China (Li, 1985). The annual life cycle described by Danzig (1980b). The main ecological characteristics for suitable growth areas of E. pela are described as annual average temperatures of between 11° and 16°C, light 1900 to 2500 h/a (hours per year), rainfall 800 to 1200 mm, and annual relative humidity between 65 and 75% (Chen et al., 2007). The distribution area exhibits different climate conditions, with the highest temperate being 44°C in the summer in Chongqing city and the lowest temperature being below −30°C in the winter in Changchun city. E. pela can establish populations and survive and reproduce normally in these conditions. This insect can survive the extremely low winter temperatures in Northeast China and can resist the drastic decrease in temperature in autumn and winter. (Zhang, et al., 2021)
• Economic Importance: A comprehensive account on the life history and commercial breeding was presented by Li (1985). The wax secreted by the male nymphs is harvested in China and processed to produce the China wax, a commodity of considerable economic value in China (Li, 1985; Qin, 1997).
• General Remarks: Good description and illustration of the adult female have been given by Danzig (1980b), Tang (1991) and by Hodgson (1994a). Good description of the adult female given by Borchsenius (1957).
