An Oregon State University researcher hopes you and your insect-loving kids will help her learn more about butterflies. Katy Prudic invites you to share pictures of the butterflies you've spotted in your travels, or your backyard, on a website: www.ebutterfly.org.  She'll use the information to learn how butterflies adapt to changes in the environment, or move to find the conditions they need to survive.  So far, about 10,000 people have been involved; but many of them are in Canada. Collection of information from amateur etymologists in the U.S. has just begun.
