Tutor description

Forensic entomology (FE) is the study of insects as it relates to criminal or civil investigations. In criminal cases, it is used to determine postmortem interval. In civil cases, FE may be used because of the introduction of insects into a consumer product or infestation of a structure. A blowfly is an insect commonly used to aid in the determination of postmortem interval. Research the use of the blowfly in determining postmortem interval. •Describe the stages of the life cycle of the blowfly? •How long is its life cycle (hours/days/weeks/years)? •How does temperature and moisture affect the length of the blowfly’s life cycle? •When time of death is in question, what is the process by which a forensic entomologist would collect samples? •What other information must an FE gather at the scene during the investigation? •What does the FE attempt to accomplish after gathering samples and information and bringing the items back to the laboratory? •How does the infestation of the blowfly aff

Through forensic entomology Medicolegal entomology is focused on the study of insects that infest on human remain. The blowfly is the most common insect found on the human body after death and provides an invaluable source of information for the forensic investigator. Once the remains of a human being have been found it will require the medical examiner conducting a forensic investigation in order to determine how long ago the victim expired. Not all victims are murdered and some die from different causes. The first step after a body is located is learning when they died. A forensic entomologist will study bug life in order to make this determination. The most important insects on corpses are the metallic green or blue flies of the family Calliphoridae (Anderson, 2010). These flies will lay eggs in the nasal opening, ears, and any place continuing mucus membranes. Forensic entomologists can also locate the eggs in bruises or wounds on the body. Once the eggs are located they provide invaluable information to the forensic investigator. When the eggs hatch they become maggots but the eggs not being hatched lets the forensic entomologists know the body has not been deceased for long. Maggots also known as larvae are what hatches from the eggs. The larvae continue to be white and shaped like a small sausage but will ha
