I have been collecting caterpillars for a week or so now and one of my students asked me a very good question. "Will the butterflies come back to our school next summer or will they go back to where I found the caterpillars?" I collected the caterpillars about 15 miles away from school in an area near my home and I bring them into my classroom. We plan to release our tagged butterflies from the classroom. Does anyone know how specific the location is that they return to the next year. I am guessing that this is one of the many questions that is still a mystery about Monarchs but if anyone has any ideas I would like to hear about them.
