1 Bugs – entomology – role of insects, TOD, collection and identity By: Zakiya & Ilexuz

2 DID YOU KNOW?! Bugs are everywhere and are used for a lot of things, but did you know they can also help scientists figure out who hit you in the head and knocked you out permanently!

3 http://www.nhm.ac.uk/about- us/news/2008/june/crime-scene-insect- investigation-boost13073.html What role do bugs/insects play in a crime scene investigation?

4 What is the first bug at a crime scene, and what is it’s life cycle ? http://ipm.ncsu.edu/AG369/notes/blow_flies.htm l, http://www.forensicentomology.com/appear.htm #bwflhttp://ipm.ncsu.edu/AG369/notes/blow_flies.htm l http://www.forensicentomology.com/appear.htm #bwfl

5 What part of the body attracts the bugs to the body and why? http://www.expertlaw.com/library/forensic_evide nce/forensic_entomology.htmlhttp://www.expertlaw.com/library/forensic_evide nce/forensic_entomology.html

6 Other than the Blow Fly, what other bugs are attracted to the corpse and at what stage do they start to appear? http://cienciaforense.com/Pages/Entomology/Ov erview.htm

7 How can the blood from a flesh eating bug contribute to solving a crime? http://science.howstuffworks.com/forensic- entomology.htm/printablehttp://science.howstuffworks.com/forensic- entomology.htm/printable

8 Does the weather determine what type of bug will invade the body and explain? http://www.sfu.ca/~ganderso/foren sicentomology.htm

9 A Case Study: Skeleton Remains of a Young Girl In Oahu, Hawaii skeleton remains were found in a shallow grave covered in dirt with bones partially exposed from the ground.

10 Stages of Decomposition

11 What Does the Future Hold? Scanning electron microscopy- A new technology created in 2007 to figure out the form and ways of an egg and maggots. Requires the use of expensive equipment. Potassium permanganate staining- When scanning cost too much this is the easier way to go. Involves only a few steps.. Mitochondrial DNA- A method created in 2001, that uses mitochondria DNA to differentiate between different species of the subfamily.
