In the world of crime, the dead may remain silent — but insects speak for them.<br />Forensic entomology is one of the most fascinating and unusual branches of forensic science, relying on the insects that colonize a body after death to uncover the time, conditions, and location of death.<br />The Honest Language of Nature<br />When decomposition begins, it releases odors that attract specific insects, especially blowflies (family Calliphoridae).<br />Within just a few hours, these flies lay their eggs on the body.<br />The eggs develop into larvae, then pupae, and finally into adult flies — each stage following a precise and predictable timeline influenced by temperature, humidity, and the surrounding environment.<br />By studying these stages, experts can estimate the postmortem interval (PMI) — the time elapsed since death.<br />When an Insect Becomes a Witness<br />Sometimes, investigators find insect species on a body that do not match the environment where it was discovered, suggesting that the body was moved after death.<br />In other cases, insects help reveal the presence of drugs or toxins in a victim’s system, as chemical residues remain in the tissues of the larvae feeding on the body.<br />Science in the Service of Justice<br />Forensic entomology goes beyond determining time of death. It provides valuable clues when other methods fall short.<br />Insects, through their patterns and behavior, become silent witnesses — immune to deceit and corruption.<br />Conclusion<br />When insects speak, they do not use words but the language of science and time.<br />Through this natural dialogue, they tell the hidden story of death and help justice see what human eyes alone cannot.<br /><br />Al-Mustaqbal University – the first university in Iraq.<br/><br/><a href=https://www.un.org/sustainabledevelopment/ar/education/ target=_blank>Goal 4</a>
