The book claims the life cycle of a blowfly, is approximately 3 weeks, therefor I believe that the flies in our experiment will mature and go through their life cycle at a faster pace because there are distinct effects in our experiment compared to the books experiment, for instance, the temperature is different. The time spent by fly immatures in the intrapuparial period comprises more than 50% of their complete life cycles. Maggot-like blowfly larvae disperse from the remains of a pig used during a field study conducted at North Carolina State University. Although it is mostly applied for investigation of a death, it is also helpful in detection of drugs and poisons , determination of the location of an incident and estimation of the time of infliction of wounds.

In this study, we determined the morphology of all stages and the developmental rate of H. Its main application is in the determination of the minimum time since death in cases of suspicious death, either by estimating the age of the oldest necrophagous insects that developed on the corpse, or by analysing the insect species composition on the corpse. His death. Forensic entomology (FE) is the study of insects as it relates to criminal or civil investigations. Flies: Flies are the first responders of the forensic entomological world, including species such as blow flies (Calliphoridae), muscid flies (Muscidae), and flesh flies (Sarcophagidae).

General Entomology Links These links are resources for budding entomologists. Crime Scene Investigator. Usually adult blow flies will deposit eggs (called oviposit) within two days of a body being dead. Next in the blowfly cycle is the was the maggot stage, this stage lasts for about 3 days and the maggots feed actively The maggots are hatched from the eggs. In forensic entomology, a way to estimate Post Mortem Interval (PMI) is to use development data of the first colonizing insects on a dead body.

After an individual dies their body begins to undergo a complex decomposition process almost immediately, attracting a variety of insects along the way who wish to colonise, feed on the temptingly putrefying remains and reproduce. Blow flies are attracted to dead bodies and often arrive within minutes of the death of an animal. According to Lessinger et al. If a body is found in a field, and the cops suspect foul play is involved, establishing the exact time of death is critical. The study of insects and their life cycles are important for forensic entomologists because it helps them determine how long an insect has been on the corpse.

Forensic Entomology is that special associated distinctive discipline of Forensic Science that deals with the assorted aspects of an insect’s or a maggot’s life cycle so as to assess the time since death. The temperature of individual blowfly larvae can be measured. The eggs hatch into first-stage maggots within 24 hours. In criminal cases, it is used to determine postmortem interval. The life cycle of a blow fly from pupa to adult occupies from 10 to 25 days, which allows from 4 to 8 new generations each season.

Once the maggots are done feeding at around day 5 of the cycle they turn to pupa. They are also used extensively in forensic entomology, predominantly to establish a minimum time since death, or a minimum post‐mortem interval, using the larval length as a ‘biological clock’. Forensic entomology is used most commonly to determine time since death. The second step is to apply knowledge of the arthropods’ life cycle in indigenous fauna to determine the age of the specimens collected (Erzinclioglu 1983; Introna et al.
