A male water mite (Arrenurus sp.) photographed under a microscope using an 8x objective. The specimen was collected in June 2023. The image clearly shows the characteristic pear-shaped body form of male water mites and their distinctive posterior extension, which is the main feature distinguishing males from females. The body surface displays a characteristic reticulated pattern and red eyes. The appendages are transparent and covered with spiny bristles. The specimen was photographed against a black background, which creates a strong contrast with the yellowish-brown body surface texture and fine details of the appendages. The lighting technique used was reflected light from a photographic speedlight flash, which particularly emphasizes the surface structures and patterns. The image was created using focus stacking technique, which ensures great depth of field throughout the subject.
