In order to identify the pests of mulberry, which is the main food source for the silkworm, in 2018-2020, monitoring of existing and newly planted mulberry orchards was carried out. Orosanga japonica first recorded on Morus sp. in the Sheki-Zagatala region located in the northwest, and then in the Khachmaz region, located in the northeast of Azerbaijan. Representatives of this family have not yet been registered in Azerbaijan. Besides of mulberry, the pest was registered in 11 more plant species. The article provides information on the distribution, phenology and plants affected by the pest. Both nymphs and adults of O.japonica cause serious damage to plants. When the females lay their eggs, it files the sprouts by the ovipositor and let them dry. Wintering is carried out in the egg phase. Nymphs begin to hatch from overwintered eggs in early May. The eggs of O. japonica were also photographed under a JCM-6000 electron microscope and given dimensions. It turned out that the surface of the egg has a peculiar microstructure (consists mainly of hexagonal and sometimes pentagonal shapes with pyramidal projections at the apex of the corners). The distribution map (scale of 1: 500000) of O. japonica in the study areas was prepared in a digital database using geographic spatial analysis using the ArcGIS (Geographic Information System) program.
