...Richard O. Prum; Jeff A. Cole; Rodolfo H. Torres SUMMARY For nearly 80 years, the non-iridescent, blue, integumentary structural colours of dragonflies and damselflies (Odonata) have been attributed to incoherent Tyndall or Rayleigh scattering. We investigated the production of the integumentary...

...Machiko Sato; Akira Azuma ABSTRACT The local circulation method was applied to the free forward flight of the damselfly Ceriagrion melanurum Selys. The kinematic data used in the calculations were obtained by analyzing video-taped images of damselflies in free flight in a transparent container...

... acting on the dragonfly were calculated. The maximum lift coefficient ( C L ) recorded from these glides was 0.93; however, this is not necessarily the maximum possible from the wings. Lift and drag forces were additionally measured from isolated wings and bodies of S. sanguineum and the damselfly...

...J. M. Wakeling; C. P. Ellington ABSTRACT The free flapping flight of the dragonfly Sympetrum sanguineum and the damselfly Calopteryx splendens was filmed in a large flight enclosure at 3000 frames s −1 . The wingtip kinematics are described for these flights. Despite the two species being similar...

...J. M. Wakeling; C. P. Ellington ABSTRACT A mean lift coefficient quasi-steady analysis has been applied to the free flight of the dragonfly Sympetrum sanguineum and the damselfly Calopteryx splendens . The analysis accommodated the yaw and accelerations involved in free flight. For any given...
