       Forensic entomology cases require appropriate collection and continuity of insect evidence as with any other evidence recovered from a crime scene. Ideally, an entomology expert is hands on to carry out these duties leading to the later analysis and interpretation of insect evidence. In the real world, the responsibility of first collection and continuity of potential insect evidence often lies with the forensic identification officers. In turn, they must pass on the evidence to the forensic entomologist. These guidelines are specifically for forensic identification crime scene officers.

       Guidelines for recognising and collecting entomological evidence from crime scenes are available in books, articles and web site publications. Forensic entomology training seminars and workshops, too, have been available in Ontario to sections of the law enforcement community the past decade or so, facilitating hands on recognition and collection of, especially, the less obvious manifestations of insects colonising remains when first encountered at a death scene and autopsy. Existing forensic entomology guidelines can be confusing to crime scene officers: There are variations in techniques and protocol offered, and methodologies to be applied by an entomologist later are confounded with the recommendations meant for immediate use by crime scene investigators.

Immediate Objectives:

       These are "bare bones" guidelines for police investigators in Ontario and beyond, as requested, covering their most immediate needs and tasks in collecting and preparing insect evidence to be passed to a forensic entomologist. The collection of Environment Canada climatological data is essential, but easily obtained later, so is not elaborated.

       This is not exhaustive in terms of a list of items needed. With an idea of what is needed, and why, then one can make use of the resources at hand.
