What Are the Steps Carried Out in Entomology in Forensics?

Entomology in forensics deals with insect evidence collected on or near a body. The forensic entomologist takes several important steps to ensure she gets all the information needed.

The study of Insects

Step 1: Observation

Investigation of the ground around the body.

Before collecting any samples, the entomologist first observes the area where the body was found, as well as the stages of maturity of any insects found on, in or around the body.

Step 2: Weather Conditions

The next thing the forensic entomologist does is get weather information. The scientist determines how warm it is at the time of collection, how warm on average it is in the area, the temperature of the site on the body where the largest concentration of maggots are, the temperature of the ground and any soil that may be beneath the body. Additionally average rainfall over the previous days is part of the research.

Step 3: Collect Fast Insects and Adults

It is very important to collect the insects that move quickly such as flies. These insects are quick to get out the area once it has been disturbed. The entomologist also collects specimens of adult insects for later study.

Step 4: Collect the Larvae

The investigator of the crime scene will collect about 60 larvae. If there is multiple areas of infestation on the body then separate larvae must be taken from each site.

Step 5: Label Everything

When dealing with sample collecting, especially for forensic entomology, the entomologist must ensure the integrity of every sample that has been taken. He also must ensure that it is properly labeled with the information on where it was taken from.

Step 6: Collection of Insects Once Body is Moved

When the body has been moved from the crime scene location, the entomologist may also collect more insects from the area.
