Handling, personnel, location, analyses, changes, must be all documented. Must be collected at scene and at autopsy. Insect species -determine which species are present on body. Length of time insects have been on body. But may be delayed by time of day, season, wrapping, freezing. Two methods of estimating period of insect colonization. Maggots or immature stages of blow flies, family calliphoridae. E. g. , 7 days, so victim dead for at least 7 days. Oldest speciments were wandering, non-feeding 3rd instar larvae. Minimum of 8. 1 days to reach the beginning of the wandering 3rd instar stage at 23 degrees (greenberg 1991) Minimum of 9. 1 days and maximum of 11. 2 days to reach the beginning of the pupal stage at 23 degrees (anderson 2000)
