The Systematics of Lasiopogon: Diptera – Asilidae

This monograph is a sturdy, hardbound volume that resulted from years of study of this group of flies limited to the Holarctic region. Dr. Cannings gives a wonderful summary of the biology and natural history of the family as a whole. It will serve as a jumping-off point for students of these flies for years to come because of its bibliographic thoroughness. C. Riley Nelson, Western North American Naturalist
