The article considers the peculiarities of the development of blood-sucking midges in the Volgograd region. Data on the species composition, breeding sites, development periods, seasonal activity are presented, and long-term data on the daily feeding activity of females are analyzed. It was found that in the daily activity of the imago, two peaks of feeding activity are observed - in the morning and evening hours, and the morning maximum is slightly higher than the evening one. The study of the species composition, ecological features of development, distribution of blood-sucking midges of the family.
