Water sources not only provide habitat for aquatic insects but also indirectly provide them with prey and other nutrients. Aquatic heteroptera, a significant group of aquatic insects, not only live in water but also play a significant role in the food chain. Also, considering the current state of water, it is known that water resources are quite limited and are dwindling daily. Therefore, it is necessary to determine and protect the quality of existing water resources. In this study, five localities in Çubuk Stream (Ankara) where under pressure of industrial and anthropogenic pollutants were identified and examined for aquatic/semi-aquatic heteroptera fauna and some environmental variables which effective on their distirbution. Samplings was made between April and September (monthly periods) at year 2025, when the seasons have aquatic heteroptera abundance is high. Some physicochemical features (pH, temperature, dissolved oxygen, salinity, and electrical conductivity) were measured at the same time the insect sampling. A total of ten aquatic/semi-aquatic heteropteran species were determined in the sampling locations. Also, it was determined that the dissolved oxygen level in Çubuk Stream was found at a critical level for aquatic organisms. But, it was thought the all observed heteroptera species have higher ecological tolerances.
