Crouching Tiger Beetles, Hidden Dragon Flies: Reflections on How Insects Use Color, Tom Schultz, Denison University

After listening to Mr. Tom Schultz talk about how we see color and how certain use colors to their advantage, I found many things to be interesting. One of my favorites would be the limitation of our ability to see color. While some organisms can only see whether there is light or no light, others can see shades of gray, humans can see an array of colors, and some insects and most birds can see an even greater range of colors than humans. The fact that birds can see ultra violet rays is interesting and not something I would have ever thought about. It was neat learning that damselfly dragonfly have iridescent wings that to us look white but other damselfly dragonflies see ultra violet colors.

I found the concept of wavelength to be a bit confusing, but it kind of cleared up as he went along. The concept that light produces different colors at different wavelengths was hard for me to wrap my head around- the fact that lighting and cell thickness can determine the color of a plant or insect only makes so much sense. I think I am getting confused because I keep trying to relate the idea of wavelength and thickness to other things such as my shirt and I am not sure if the idea transfers over to non-organisms.
