Forensic Entomology for the Crime Scene Investigator


Forensic entomology is the use of insects and their arthropod relatives to aid legal investigations. The proper identification of the insect and arthropod species present in a forensic entomology case is important. The genus/species identification helps the forensic entomologist retrieve the correct developmental data and distribution ranges needed for the case. An incorrect identification can lead to a potential error in the estimations and effect the estimation of the total postmortem interval.

Cost: $125.00. This course takes 15 hours to complete, on average.


At the end of this course, students will be able to:

  • Define entomology and forensic entomology
  • Describe three basic areas of forensic entomology
  • Define the body regions of an insect
  • List the taxonomic categories of insects
  • Describe the development stages of a fly
  • Discuss the forensic importance of flies
  • Describe the basic anatomy of a beetle
  • Describe the differences between the forensically important beetles
  • Discuss how insects and arthropods, other than flies and beetles, are forensically important
  • Describe the scavenging arthropods and their significance to forensic investigations
  • Define postmortem interval
  • Describe how entomological evidence can help in estimating postmortem interval
  • List the factors that can influence the insect succession and insect development
  • Describe sampling of arthropod specimens for collection.
  • Define ecological succession and how it relates to forensic entomology
  • Describe the five stages of decomposition and the insects associated
  • Discuss the different applications that DNA analyses can be used for in forensic entomology
  • Describe drug and toxin impact on insects and insect developments
