2  Trowel › Used to dig up soil sample

3  Thermometer › Used to take temperature of air and maggot mass

4  Forceps › Used to collect crawling insects

5  Secure, ventilated jars › Larvae need air to breathe until they are reared in the lab to determine species and development rate › Keep insects separate – will kill each other

6  Capped Specimen Jars › Contain 70% ethyl alcohol solution › Preserve specimen in order to “stop” their biological clock

7  Portable Weather Station › Used to gather weather data for five to seven days to establish pattern

8  Hand-net › To collect flying insects

9 1. Look at fauna and test soil Why is this important? To see if body has been moved 2. Collect specimens from different areas of the body, clothing, surrounding environment (indoor/outdoor) 3. Collect 100 maggots

10 4. Collect pupae from body, clothing, hair, soil 5. Collect empty pupal cases from body, clothing, and surroundings 6. Collect adult flies 7. Collect beetles Feed on cartilage and bone of corpse

11 8. Collect any other insects at scene 9. Collect leaf litter near remains of body if outdoor Collect enough to fill coffee can 10. Place all insects in vials with food Usually use beef liver – keeps insects alive and feeding on protein

12  Keep insects collected from different parts of the body separate from one another › May be different species › Cannibals – will eat each other

13  When would insects not be present on a body?

14 › If body is wrapped in plastic  Insects would not smell the corpse › Buried deep underground › Frozen/freezing temperatures  Bugs don’t live
