Structure and Function of a Katydid | Iowa Science Phenomena

Katydids are hard to find. Is it a coincidence that they are green, or is there a purpose for their color? What other animals seem to have traits that are advantageous to their survival? What role does the environment play in this advantage? Do other features of the katydid (besides color) also help it? Do only prey exhibit advantageous traits, or do predators as well? Investigate the different traits of katydids.
