The eggs of the *E. Integriceps* are spherical and measure about 1 mm of diameter [48]. At the time of oviposition, eggs look light green, which eventually turns

dark as embryo matures [50]. *E. integriceps* has five nymphal instars [51–53]. First instars measure 1.5 mm in diameter and light in color. Nymphs look similar to adults except with 2–3 paired black dots in the midline between the lateral margins of the abdomen. The nymphs cannot be illustrious from closely related spp. and must be identified at adults [53].

Adults are elongated and elliptical, and their color varies from grayish to brown, to red or black [54]. In this concern, Color of the *E. Integriceps* is extremely uneven and has no worth for biosystematics identification [55]. Adult length and width measures 10–12 mm and 6.1–7.1 mm respectively. There is only one generation per year and an obligatory diapause in the adult stage [56–58].
