[Expert insect identification in cases of decomposed bodies].

We report two cases in which putrefied corpses were found in the state of massive myasis (colonisation of files); in one case, also beetles could be collected. Case 1:A human corpse was found four months postmortem exposed freely near a railway embankment (suicide, known heroin user). Masses of jumping cheese skipper fly larvae were found on the corpse and bred for identification subsequently. Furthermore, several beetles were found. Case 2: Three months after removal of a corpse found dead for one and a half month in fall/wintertime in a flat, green-blue blowflies and their larvae were seen constantly in the now completely empty, disinfected flat and in a flat being situated in the floor below. Larvae hid behind vertical floor ledges and wall-on-walls made of plaster and rested in diapause until temperature increased.
