Entomology - study of insects
Forensic Investigations
ASISTM, 2006
InsectsInsects are a class of Arthropods that have three segments to their body, one pair of antennae, three pairs of legs, compound eyes and breathe air via small holes or spiracles along the side of their body.
InsectsMost arthropods are insects BUT there are also bugs that are NOT insects such as spiders (Arachnida), crayfish & woodlice (Crustacea) and millipedes & centipedes (Diplopoda & Chilopoda - sometimes collectively known as Myriapoda).
It is easy to be confused!
InsectsClassification of the arthropods can also be slightly different in various information sources.
To make it even more confusing, as more research is done, scientists may revise or even change what group various organisms belong in.
InsectsAs you watch the slide presentation, think about the following:
• Are there ‘good or bad’ insects?
• What role do insects play in science?
• Are insects important in forensic science?
