One of the most significant biological limits on rice productivity is insect pests, but the extent of the damage depends on the crop's growth and the number of biotic and abiotic pressures that are influencing it. The study's objective was to evaluate the distribution, biology, and damage caused by novel insect pests in three rice-growing regions in Ethiopia's South Gondar Zone in 2021. Visual evaluation was used to identify the insects and to gather additional natural enemies using hand nets. Taxonomic keys were used to identify natural enemies morphologically. In this experiment, the natural enemy density was calculated using the frequency of insect pest presence on rice plants at various locations using 2m2 quadrants. The biology of the insect was studied by using rearing cage in the FNRRTC entomology laboratory. The result implied that the insects, Creatonatos sp. found in all assessed area, and found in both upland and lowland rice. Even though, the insect found in all the assessed area, its damage seams less. The survey also found the diversity of natural enemy on rice paddy in south Gondar Zone. From the biological study Creatonatos sp are Holometabolous (Complete metamorphosis), insect life cycle passes 4 stage, which are egg, instars, pupa, and adult.
