Forensic entomology includes the analysis of organisms colonizing various parts of the body in order to determine the circumstances of an incident, mainly the time, place, and cause of death. The presence of insects and other arthropods on carcasses can be a source of knowledge for the judicial system. However, this type of research (on submerged bodies) is less published. The aim of our study was to analyse the qualitative and quantitative structure of macroinvertebrates colonizing potential evidence in an upland river. The experimental research involved an eight-week exposure to articles of clothing made of different materials: natural materials (bottom sediments with plants from a river), synthetic (socks), and cotton (t-shirts). Control samples of water after 2, 4, 6, and 8 weeks were taken from experiment locations in the River Bystrzyca with a tube apparatus and hand net. The results indicated that the abundance of organisms on a given substrate depended on the period of development of invertebrate macrofauna and the time of exposure of the substrates. The abundance of aquatic macrofauna on the exposed items increased in direct proportion to the duration of the experiment, which may indicate the adaptability of these organisms to new habitat conditions. Among the taxonomic groups used in forensic entomology, Diptera, Coleoptera, and Odonata were the most abundant. The remaining taxa (including Heteroptera), though not widely used in judicial proceedings, can also provide valuable information about the circumstances of an incident.
法医昆虫学包括分析寄生于尸体各部位的生物，以确定事件的情况，主要是时间、地点和死因。昆虫和其他节肢动物在尸体上的存在可以为司法系统提供知识来源。然而，这种（对水下尸体的）研究发表的较少。我们的研究目的是分析在一条山地河流中潜在证据上寄生物的定性和定量结构。实验研究涉及将不同材料制成的衣物（河流底部沉积物中的植物、合成纤维（袜子）和棉（t 恤））暴露于水中 8 周。从比斯特里察河的实验地点用管状仪器和手抄网采集了第 2、4、6 和 8 周后的水样对照样本。结果表明，给定基质上生物的丰度取决于无脊椎动物大型动物群发育阶段和基质暴露时间。暴露物品上水生大型动物群的丰度与实验持续时间成正比增加，这可能表明这些生物对新栖息地条件的适应性。在法医昆虫学中使用的分类群中，双翅目、鞘翅目和蜻蜓目是最丰富的。其余的类群（包括半翅目）虽然在司法程序中未广泛使用，但也可以提供有关事件情况的有价值信息。
