Gender

Is it possible to tell if my caterpillar is a boy or a girl? I did some research and found that basically the only way to tell is dissect him and look for certain parts. Other ways would be to put it in alcohol and observe it through the transparent skin. Unfortunately, both of those methods would kill my little caterpillar and I need him to stay alive until he flies for my project. The site I looked at mentions that male caterpillars are typically more colorful and brighter, while females are larger in size. Perhaps when he flies I will be able to compare him to others and guess if he is male or female. 

Here's a reference in case you want to dissect your caterpillar. There are step by step instructions for determining the gender. http://www.ehow.com/how_5911369_determine-caterpillar-male-female_.html
