Christine, we can tell it's a Hairstreak and that's good enough for me! They aren't always the most cooperative butterflies.
Ann, I have heard people say the plural of chrysalis is either chrysalises or chrysalids. The first one sounds better to me so that's the one I use. As for the color thing, it doesn't seem like it would be that hard to do an experiment. Man, I wish I had thought of this when I was still in school. I used to have the worst time thinking up science projects. In 3rd grade I did go to the county science fair and won a trophy. It was like the second place award. I never let my friend, and rival, in the gifted program with me forget it, either!
We had learned about different soils that year. I thought everything was sand or red clay (like on the kickball field) until then. My favorite was vermiculite. I've always like words that begin with "V" and I liked the texture. So I did an experiment where I grew pinto beans (suggested by Dad for their quick growth rate) in different soils. As I recall, potting soil did best and sand from my yard did the worst.
That's Florida, for you. You gotta add amendments to your soil!
