19. Use the charts on the Crime Solving Insects
reference card to determine the age of the
maggots listed in the chart.
20. Explain how a forensic entomologist would use fly larva to estimate the PMI.
1st – Collect maggots from the body along with other insect evidence.
2nd
– Identify the species of each insect species present.
3rd
– Determine the length of the maggots and use weather data to estimate the ages
4th
– Use the insect evidence along with
temperature, etc.) to estimate the length of time that had passed since death

Answers will vary.
Collect maggots from the body along with other insect evidence.
Identify the species of each insect species present.
Determine the length of the maggots and use weather data to estimate the ages
Use the insect evidence along with other factors (stage of decomposition, condition of body, body
temperature, etc.) to estimate the length of time that had passed since death
