Insects are known to be useful in estimating the postmortem interval (
PMI). Here several cases are reported which show that a wide range of
applications in medicolegal questions and hygiene together or apart fr
om estimating the PMI can be answered by use of forensic entomology te
chniques, including dose observation of larval development. Case 1 des
cribes how blowfly larvae fell from a putrefied corpse, hid, and final
ly emerged from pupae three months after disinfection and renovation.
In case 2, the entomological state of the decomposed corpse of a heroi
n user is described. Case 3 deals with a single adult Protophormia ter
ranovae found in the skull of a partially mummified woman. Case 4 repo
rts the finding of Serratia marcescens bacteria in red Muscina stabula
ns pupae which were found on a 5-day-old corpse. In case 5, blowfly eg
gs on the corpse of another heroin user are interpreted as an indicati
on of the decedent being laid outside at night after his death in a fl
at. Case 6 deals with the finding of Parasarcophaga argyrostoma, which
in Cologne might be an indicator species which tells if a corpse was
lying outside at least for some time.
