86th Annual Meeting of the American Society of Mammalogists, University of Massachusetts, Amherst, Amherst, Massachusetts.

1. The Effects of Bot Fly Parasitism on Movements of Peromyscus leucopus Michael J. Cramer and Guy N. Cameron University of Cincinnati

4. Rodent Bot Fly Life Cycle Females lay eggs in host habitat. Hosts pick up newly hatched larvae . Larvae migrate to inguinal region and develop warble. After 3 rd instar, larvae exit host and burrow underground to pupate. Flies emerge and mate at aggregation sites. 5 days 21 days P. Meyer C. N. Shiffer M. J. Cramer
