Abstract
Insects play an essential biological and ecological role in human life, and their predictable relationship with decomposing remains has positioned them as a cornerstone of modern forensic science. Since the early 20th century, forensic entomology has provided critical evidence for estimating the postmortem interval (PMI), relying on patterns of colonization, species succession, and insect developmental timelines. Accurate PMI estimations are vital to medicolegal investigations, influencing the interpretation of biological evidence, guiding resource allocation, and informing determinations of cause and manner of death. However, insect activity is profoundly shaped by environmental and ecological variables, including temperature, humidity, seasonal shifts, and geographic context, all of which can alter species availability and developmental rates. This study examines how these abiotic factors affect insect succession and, consequently, the reliability of PMI estimations across diverse environments. Ultimately, forensic entomology’s strength lies in its integration of insect biology, ecology, toxicology, and traditional forensic methodologies. As analytical techniques continue to advance, entomological evidence will remain a scientifically grounded and ethically informed tool for reconstructing death events and strengthening the accuracy of criminal investigations.
