College for their help in establishing a laboratory colony of Mon- 
arch butterflies. I would also like to thank Ms. Mary Kanz for her 
assistance throughout the field studies. This research was sup- 
ported, in part, by funds derived from an NIH Career Develop- 
ment Award to Dr. K. D. Roeder, Tufts University.
