HORTICULTURE

Detailed explanation-1: -The larvae (maggots) molt into multiple instars before the formation of the puparia and the emergence of the adult. The timing of each of these growth stages has been researched, enabling this information to be used to estimate time since death.

Detailed explanation-2: -FORENSIC ENTOMOLOGY : THE USE OF INSECTS. Forensic (or medico-legal) entomology[1] is the study of the insects associated with a human corpse in an effort to determine elapsed time since death.

Detailed explanation-3: -Because flies rapidly discover a body and their development times are predictable under particular environmental conditions, the time of death can be calculated by counting back the days from the state of development of flies living on the corpse.

Detailed explanation-4: -Insects arrive at a decomposing body in a particular order (succession) and then complete their life cycle based on the surrounding temperature. By collecting and studying the types of insects found on a body and their metamorphic stage, a forensic entomologist can estimate the time of death.
