Investigators can use the distribution, biology, and behavior of arthropods collected at a crime scene to determine when, where, and how the crime was committed. The type and species of fauna discovered on a body indicate its decomposition stage. Blowfly larvae play a vital part in the breakdown of animal remains, which is an important ecological function. To illustrate this further, the bodily dimensions and developmental stages of blowflies found in or on a dead body are used by forensic entomologists to calculate the time elapsed between death and discovery of a corpse which is also referred to as the post-mortem interval (PMI). Temperature is a well-known abiotic element that influences the growth of blowflies. Time-temperature interaction has been reported as a determinant of insect survival. The shortest time from oviposition to adult emergence in insects is inversely related to temperature, and the developmental time from oviposition to adult fly eclosion may vary by region. Previous growth experiments on blowflies at various temperatures have confirmed this link. The growth rate of these arthropods, particularly fly larvae, is influenced by a variety of conditions, thus it must be rigorously researched. Many investigators have employed a variety of food substrates in the past to test various aspects of forensic entomology. A variety of rearing media, including different species of animal and tissue types, are used in published studies (e.g., muscle and liver). The nutritional requirements of larvae are likely to differ depending on whatever section of a corpse they are feeding on. In the present review paper, the role of temperature and diet on various developmental stages of blowflies has been discussed. Limitations to the field's expansion have been identified, as well as the way forward for further research.
