In this study, we investigated the features of chromosomal polymorphism of Chironomus tentans Fabricius, 1805 (Diptera, Chironomidae) larvae, collected from several water bodies of Kaliningrad. In the karyotype of C. tentans, there have been found 16 banding sequences, 19 genotypic combinations, and 23 zygotic combinations. The average number of heterozygous inversions per specimen was calculated. The frequencies of banding sequences were calculated. A comparison with the similar data has been carried out. The greatest polymorphism was observed in the shoulders A, B, F.

Keywords:Diptera, Chironomidae, Chironomus tentans, polytene chromosomes, karyotype, chromosomal polymorphism, Kaliningrad
