This study employed water mite (Acari, Hydrachnidia) species collected from a natural lake water environment. These species included Hydrodroma despiciens, Eylais infundibulifera, Hydryphantes flexiosus, Georgella helvatica, Hygrobates nigromacutlatus, Hydryphantes thoni ve Torrenticola bevirostris. Chemical analyses of these species were conducted using the Fourier infrared spectrophotometer (FTIR) technique. Solid phase IR spectra were made individually for each species. The data obtained for all species were examined graphically and were identified in four different spectral regions. Finally, the spectrum frequency ranges of these species were determined. The functional groups OH, C-H, C=O, C-O, and C-N were observed. The vibrational frequencies of each species studied were determined. When evaluating the results of the spectroscopic analysis, the range of the spectrum of these species was shown to be similar to one another; however, peak intervals were different for each species.
