Title: "Spray Mechanism of African Bombardier Beetles". A silent color film by Harold E. Edgerton, D. Aneshansley and T. Eisner demonstrates the spray mechanisms of several types of bombardier beetles (Ozaenine Carabid, Metrine Carabid). Chemical indicator paper placed beneath each beetle allows the scientists to capture the direction and intensity of the emissions sprayed when the beetle is poked. Title cards explain the details and distinguish between images shot at the normal speed of 24 fps and at the high speed of 400 fps. The research was a collaboration with the New York State College of Agricultural and Life Sciences at Cornell University (likely in early 1980s). Run time = 00:09:34. (EH, CC)
