Insects from the bodies of illegally hunted rhinoceros may provide valuable forensic information

New research in Medical and Veterinary Entomology reveals that when rhinoceros are found dead after being illegally killed by poachers, analyzing insects on the decomposing body aids in estimating the time since death. This information has been used by investigators and officials to construct cases against suspected perpetrators.

The study included 19 rhinoceros that were illegally killed and dehorned in the Republic of South Africa between 2014 and 2021. Scientists collected 74 samples of insect evidence from these rhinoceros remains, from which an accurate estimate of their time of death was calculated. The specimens comprised 18 species from 12 families belonging to three insect orders.

“This has implications across both the science of forensic entomology and forensic wildlife, and especially highlights the opportunities for improving the global understanding of the procedures related to wildlife criminal cases,” said co–corresponding author Ian R. Dadour, PhD, of Source Certain and Murdoch University, in Australia. “Over the last 30 years, the results of this new activity combined with ranger teams and satellite tracking have led to a rebound in rhinoceros populations.”
