Meeting Abstract S1-4.5 Jan. 5 Role of antennae in insect flight control SANE, SP*; DIEUDONNE, A; DANIEL, TL; University of Washington, Seattle; University of Washington, Seattle; University of Washington, Seattle sane@u.washington.edu The antennae of flying insects perform multiple sensory functions. In addition to being the primary olfactory organs, antennae serve an important mechanosensory role during flight. For […]

Locomotor biomechanics of a free-ranging gliding mammal (Cynocephalus variegatus)
Meeting Abstract S1-4.10 Jan. 5 Locomotor biomechanics of a free-ranging gliding mammal (Cynocephalus variegatus) BYRNES, G. T.*; SPENCE, A. J.; Univ. of California, Berkeley; Univ. of California, Berkeley byrnes@berkeley.edu One of the biggest challenges in comparative biomechanics is to describe the locomotor performance of animals in their natural environment. This is important because measures of performance in […]
Is the Annas Hummingbirds dive-noise vocal or non-vocal
Meeting Abstract S1-4.7 Jan. 5 Is the Anna�s Hummingbirds� dive-noise vocal or non-vocal? CLARK, C.J.; Univ. of Calif., Berkeley cclark@berkeley.edu Male Anna�s Hummingbirds (Calypte anna) perform display dives in which they fly 30-50m up in the air, then dive head-first towards a perched female. At the bottom of the dive, they emit a loud noise called the […]
From Vogelian Imagination to Gaseous Machinations Animal Flight Performance in Variable-Density Air
Meeting Abstract S1-4.2 Jan. 5 From Vogelian Imagination to Gaseous Machinations: Animal Flight Performance in Variable-Density Air DUDLEY, Robert; Univ. of California, Berkeley wings@berkeley.edu Animal flight performance is typically studied at or near sea level within the contemporary atmosphere. Experimental alteration of the physical composition of gas mixtures, however, permits construction of novel flight media and the […]
Creating a flap Different ways to wing it
Meeting Abstract S1-4.3 Jan. 5 Creating a flap: Different ways to wing it HEDRICK, TL*; DANIEL, TL; Univ. of North Carolina, Chapel Hill thedrick@email.unc.edu Hovering insects appear to precisely maintain their position and orientation while flapping with nearly unchanging wing motions. However, simulations of hovering flight in the hawkmoth Manduca sexta suggest maintaining position and orientation over […]
Barbs of a Feather Bend (and Twist) Together
Meeting Abstract S1-4.9 Jan. 5 Barbs of a Feather Bend (and Twist) Together JOHNSON, A.S.*; ELLERS, O.; BUTLER, M.; Bowdoin College, Maine ajohnson@bowdoin.edu We propose the following design principle for feather barbs. By being thicker-walled dorso-ventrally, their flexural stiffness is increased during flight; but by allowing for twisting when loaded with dangerously high forces they firstly avoid […]
A new insect flight model is just around the bend
Meeting Abstract S1-4.4 Jan. 5 A new insect flight model is just around the bend MOUNTCASTLE, A.M.*; DANIEL, T.L.; Univ. of Washington, Seattle; Univ. of Washington, Seattle mtcastle@u.washington.edu Models of insect flight commonly assume wings behave as rigid airfoils. Many insect wings are flexible, however, with dynamic bending occurring as a consequence of flapping flight. In moths, […]
Work of Detachment is Controllable in Gecko Setal Arrays
Meeting Abstract S1-3.5 Jan. 5 Work of Detachment is Controllable in Gecko Setal Arrays GRAVISH, N*; WILKINSON, M; AUTUMN, K; Lewis & Clark College; Lewis & Clark College; Lewis & Clark College autumn@lclark.edu Gecko setae are anisotropic in adhesive function. Comprised of thousands of angled hairs, setal arrays attach strongly when dragged along their natural curvature. […]
Towards a realistic model of insect locomotion
Meeting Abstract S1-3.8 Jan. 5 Towards a realistic model of insect locomotion KUKILLAYA, R.P.*; HOLMES, P.J.; Princeton University, New Jersey; Princeton University, New Jersey rkukilla@princeton.edu We develop a hexapedal model to describe insect locomotion in the horizontal (ground) plane. The head-thorax-body is modeled as a single rigid body, and leg masses and inertias and joint dissipation are […]
The Relevance of Resonant Frequency in Running Cockroaches Modeled by a Spring-loaded, Inverted Pendulum
Meeting Abstract S1-3.2 Jan. 5 The Relevance of Resonant Frequency in Running Cockroaches Modeled by a Spring-loaded, Inverted Pendulum DUDEK, DM*; SRINIVASAN, M; ROGALE, K; KUKILLAYA, R; HOLMES, P; FULL, RJ; Univ. of British Columbia; Princeton Univ.; Princeton Univ.; Princeton Univ.; Princeton Univ.; Univ. of California, Berkeley dudek@zoology.ubc.ca An array of morphologically diverse runners, from insects to […]
