Forensic entomology is the study of insects in relation to a deceased person, and has proven useful in the field of forensic science, due to the versatility in how these insects are analyzed. The defined life cycle of certain insects allows for the various stages of development to be used in determining time of death, whether the body has been moved, and many other elements of a crime (James, Nordby, 2005). Insects can be analyzed by their stage in the lifecycle, what region they come from, what they have ingested when feeding, etcetera. As useful as insects have proven in investigations, they also have the ability to contaminate crime scenes and cause problems for forensic investigators.
The most common insect used for identifying time of death in the field of forensic entomology is the blow fly, because they are most often the first insect to colonize the body (James, Nordby 2005). Blow flies arrive at a body within ten minutes of catching its scent and lay their eggs soon after (Shipman 2011). The average lifecycle of a blow fly is “16 to 35 days, depending on temperature and environmental conditions” and begins with the larval stage (Texas A&M). The larval stage itself is divided into first, second, and third instar stages (James, Nordby 2005). A first instar larvae are weak and lack the mouthparts necessary to break skin, so the female blow fly will deposit her eggs near an open wound or the natural orifices of the body, where the larvae can feed on the liquids present (James, Nordby 2005). Second instar larvae are stronger, larger, and have special proteolytic enzymes they use to enter the body (James, Nordby 2005). Proteolytic enzymes are “any of a group of enzymes that break the long chainlike molecules of proteins into sh...

Essay on Forensic Entomology - Forensic Entomology Forensic entomology is the study of insects and arthropods and their relation to a criminal investigation. Forensic entomology can determine the postmortem interval (PMI) or how long since the descendants’ death, whether the body has been moved since expiring, and what injuries may have been sustained (Ryan, 2011). When decomposition begins, insects establish a colony to lay eggs on the remains; these eggs will hatch into larvae that will eat the human organs and tissues. Forensic entomologists can determine the specific insects present in the body and estimate how long a body has been left exposed by examining the stage of development of the fly larvae; however, these f...   [tags: Criminal Investigation, Maggot] 1178 words

Forensic Pathology as a Career Essay - Forensic Pathology as a Career The career that I researched was forensic pathology. The job of a pathologist is to determine a person’s cause of death by examining tissues and fluids from the body. A forensic pathologist does this as well, but they are trained to examine people who died unexpectedly or violently and to recognize other things that a regular pathologist might not, such as recognizing something as intentional rather than accidental. They have to determine who the person is, the time of death, the manner of death, and if it was accidental, the instruments which caused the death....   [tags: Forensic Pathology Careers Medical Essays]

Forensic Linguistics Assignment Essay - Speech analysis has a type called the voice stress analysis that detects stress in the form of micro tremors in the speech of a person. It is important to note that the voice stress analysis is equivalent to polygraph. Both polygraph and stress have a common problem of not being able to point out deception. This notwithstanding, the speech analysis is apparently being used by both the Federal Bureau of Investigations and the Central Intelligence Agency of the United States. The fact that each and every person possesses a unique voiceprint makes the identification of a speaker to be theoretically possible....   [tags: Forensic Science ]
