The use of insects and associated arthropods in legal cases : a historical and practical perspective

 Forensic entomology has generally been recognised among law enforcement and the wider community as a science employed in the estimation of time since death. The utility of this science in contributing to the provision of time frames resulting in the focusing of valuable investigative resources has certainly been of the greatest importance. However, arthropods have been exploited extensively for their ability to provide information in a multitude of other situations, including cases of neglect, the food industry, and information relating to the cause and manner of death. This chapter will discuss the realm of information obtainable from insects and related groups in the forensic context, including and beyond the recognised time since death applications. Two areas of current research, molecular forensic entomology and entomotoxicology, will be discussed for their potential impact in the field.
