Burial of a body prevents many insects from getting to the body therefore slowing down decomposition. The only bugs known to reach a body once it has been buried are blowfly larvae, flesh fly larvae and coffin flies. (Fraser 2015, Per Comm). Environmental factors can also affect the way insects attend a body. During winter most insect activity is reduced. Sometimes blowflies may not be seen at a body until spring time therefore during colder weather bodies decompose more slowly than during the warmer months. (Fraser 2015, Per Comm). It is important to know the temperature of the crime scene so an accurate time of death can be achieved based on the growth of the insects. If it is cold the insects are more likely to remain smaller for a longer period of time than if
