How to identify the mouthparts of insects...
Can you identify mouth parts in bugs? Why do they evolve in such a way?
Today we will practice making observations from specimens of real-life bugs.
Look at the chart below and see how different types of mouth parts, referred to as chelicerates, typically look:

A) Jacknife
B) Scissor
C) 3-segmented chelate
Chelicerae are chalete appendages that insects use to grasp food. For example, carnivores have chelicerae to tear and crush prey, while herbivores are used to pierce and suck food. The mouthparts of insects have evolved in forms adapted to their mode of feeding. Look at this picture of a scorpion and write down your observations in your scientific journal. After you've listed your observations, we will try to identify the type of chelicerae by comparing your notes to the chart above.
