A New Marking Technique for Studying the Mating Behavior of Odonata

Kenneth W. Knopf

Fluorescent pigments mixed with vaseline are applied so that some of the paste is transferred during mating. Application is to the male caudal appendages or their points of contact on the female. An ultraviolet light is then used to check field collected individuals for transferred pigment.
