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
