2. What is forensic entomology?
Forensic entomology is the study of arthropods,
especially insects, associated with crimes and
other aspects of the courts and judicial system.
Forensic entomology usually involves the
identification of insects and other arthropods
associated with human remains as an aid to
determining the time and place of death.
Role of insects in forensic
science?
By studying the insect population and the
developing larval stages, forensic scientists
can estimate the postmortem index, any change in
position of the corpse as well as the cause of
death.

3. used to
determine time
of death?
An analysis of the
oldest stage of insect
on the corpse and the
temperature of the
region in which the
body was discovered
leads to a day or
range of days in which
the first insects
oviposited or laid
eggs on the corpse.
This, in turn, leads
to a day, or range of

4. Blowflies are often the
first insects to colonize a
corpse, attracted by the
odor of decomposition.
Forensic entomologists can
analyze the developmental
stages of blowfly larvae
found on or near the body
to estimate the time of
death. By determining the
age of the larvae and
considering environmental
factors like temperature,
they can provide a fairly
