In forensic entomology, (clockwise from top left) blow flies, flesh flies, carrion beetles, and rove beetles are common visitors to the scene of death and decomposition. Big Idea 2: Specie succession is an essential principle in forensic entomology.-Why are species successions important in Forensic Entomology?The can tell investigators the PMI of a body.-How do Entomologists use species succession to determine the time of death?Different species arrive and develop on a decaying corpses at different time in the decay process. Required fields are marked *. Metamorphosis Process by which an organism undergoes distinct changes from young to adult form. Adult beetles were collected as early as 24 h after death. Forensic entomology is a discipline that deals with the study of those forensically important insects and the testimony dealing with such insects in criminal proceedings( Byrd, Castner 2001). Nowadays, it has become an important branch of forensic science. Keywords: Forensic entomology, insect succession, blow flies, decomposition, carrion Blow flies are the first and most common insect to arrive on a corpse. Physical barriers can be intentional or unintentional, but the end result often alters insect colonization and decomposition. House flies arrive when the body reaches bloat stages in decomposition. when the body begins to dry blow flies do not find the body as suitable.
