After death of a living organism, the activity of insects is the main mechanism by which decomposing organic matter returns to the nutritional chain. However, it is necessary to consider that this activity can imply modifications of great taphonomic and forensic interest. If its magnitude is not known well, it can induce to error in the later analysis of the forensic pathologist. In this article, we give an organized classification of the different taphonomic phenomena induced by insects (addition, elimination and modification of the corpse) and enunciate the differential features that allow to separate them from similar pathological processes, focusing our attention on the orders Coleoptera, Diptera and Lepidoptera as the main responsibles of these modifications.
