Forensic entomology uses the biology of which organisms to aid investigations?

Forensic entomology specifically involves the use of insects and their developmental stages to aid in criminal investigations. This field of study is based on understanding how various species of insects are attracted to decomposing organic matter, such as carcasses, and how the timing of their life cycles can provide crucial information about the time of death.

Insects, particularly blowflies and beetles, are often the first organisms to arrive at a corpse, and by examining the types of insects present and their developmental stages, forensic entomologists can estimate the post-mortem interval—or the time since death. This information can play a pivotal role in criminal cases, helping to establish timelines and corroborate evidence.

Other organisms like birds, mammals, or reptiles do not typically have the same consistent and well-studied relationships with decomposition in forensic contexts as insects do, making insects the primary focus for entomological investigations in forensic science.
