Monarch butterfly that is. On a nice breezy Saturday morning in late September 2010, I was attending the annual Fall Fishing Derby sponsored by Urban American Outdoors. Kids were fishing in the nearby pond and I was on hand to do some urban ecology and environmental science outreach.

When I caught something moving along...

I told the kids that this Monarch Butterfly most likely encountered a bird like a robin or blue jay or starling that was hoping for a quick meal. The bird soon realized that this butterfly was bitter and awful tasting and spit the butterfly out. This chemical defense tactic against the butterfly's predators. It helps butterfly populations to survive; but it doesn't help the unfortunate individual who taught the bird a lesson. So there is a sacrifice of individuals that benefit the masses (altruism).
