In the world of forensic science, the search for truth is not limited to DNA or fingerprints — it also involves tiny creatures that play a crucial role in uncovering hidden secrets: flies and insects.
This fascinating field is known as Forensic Entomology, a branch of biology that studies the relationship between insects, death, and criminal investigations.
What Is Forensic Entomology?
Forensic entomology focuses on the insects that colonize a body after death. By analyzing their species and stages of development, experts can estimate the postmortem interval (PMI) — the time since death — and sometimes determine the location or whether the body was moved.
The most common insects used in this field are blowflies (family Calliphoridae), which lay eggs on a corpse within hours of death. These eggs develop into larvae and pupae following predictable patterns that can be matched to a timeline.
How Do Flies Help Serve Justice?
Different insect species thrive under specific environmental conditions such as temperature, humidity, and light. By collecting larvae and adult flies from a crime scene, forensic scientists can estimate when death occurred.
In some cases, the discovery of unusual insect species on a body can indicate that it was moved after death, revealing important clues about the crime.
Other Applications
Forensic entomology is not limited to human deaths. It also contributes to investigations involving animal deaths, poisoning, food contamination, and even illegal trafficking of wildlife.
Conclusion
Forensic entomology demonstrates that every living creature, no matter how small, can become a witness to crime.
