The egg of Ochlerotatus japonicus japonicus (Theobald) is described with the aid of variable pressure scanning electron micrographs. The egg is black, cigar shaped, and tapers ventrally. The length is approximately 591 microm and the width is approximately 172 microm. The outer chorionic cells are irregular in shape, either hexagonal or pentagonal, and decrease in size toward the anterior and posterior poles. Ventral tubercles typically range from three to six and contact the chorionic reticulum. Dorsal tubercles contain two large tubercles with small oval-shaped tubercles grouped around them. A large thread-shaped tubercle extends from this grouping either as a single tubercle or as a series of connected tubercles. The micropylar collar is low and discontinuous and is seldom complete. This description will aid researchers in the identification of this invasive vector species.
借助可变压力扫描电子显微镜图像对日本伊蚊（Theobald）的卵进行了描述。卵呈黑色，雪茄形，腹侧逐渐变细。长度约为591微米，宽度约为172微米。外层绒毛膜细胞形状不规则，呈六边形或五边形，在前极和后极处尺寸减小。腹侧瘤通常为三到六个，并与绒毛膜网状结构接触。背侧瘤包含两个大瘤，周围有小的椭圆形瘤聚集。一个大的丝状瘤从这个聚集处伸出，要么作为单个瘤，要么作为一系列相连的瘤。卵孔环较低且不连续，很少完整。该描述将有助于研究人员识别这种入侵媒介物种。
