Predation and the Flight, Morphology, and Temperature of Neotropical Rain-Forest Butterflies
The morphological traits, flight speeds, and temperatures of 54 species of common Neotropical rain-forest butterflies in Corcovado National Park, Costa Rica, correlate with their palatabilities.Expand

Unconventional lift-generating mechanisms in free-flying butterflies
TLDR
We trained red admiral butterflies, Vanessa atalanta, to fly freely to and from artificial flowers in a wind tunnel, and used high-resolution, smoke-wire flow visualizations to obtain qualitative, high-speed digital images of the air flow around their wings. Expand

Dragonfly flight: free-flight and tethered flow visualizations reveal a diverse array of unsteady lift-generating mechanisms, controlled primarily via angle of attack
SUMMARY Here we show, by qualitative free- and tethered-flight flow visualization, that dragonflies fly by using unsteady aerodynamic mechanisms to generate high-lift, leading-edge vortices. InExpand

Locomotor Mimicry in Butterflies? The Associations of Positions of Centres of Mass among Groups of Mimetic, Unprofitable Prey
With detailed measurements of flight-related morphological parameters of 18 species within the tribe Heliconiini and 10 of their non-heliconiine comimics, I found that morphological parametersExpand

Directed aerial displacement requires that a volant organism's airspeed exceeds ambient wind speed. For biologically relevant altitudes, wind speed increases exponentially with increased height aboveExpand

Magnetoreception in eusocial insects: an update
Behavioural experiments for magnetoreception in eusocial insects in the last decade are reviewed. Ants and bees use the geomagnetic field to orient and navigate in areas around their nests and alongExpand

Flight morphology of Neotropical butterflies: palatability and distribution of mass to the thorax and abdomen
SummaryWe test whether palatability of Neotropical butterflies is associated with distribution of mass to the thorax and abdomen. Thoracic mass is predominantly muscle mass, whereas abdominal massExpand

Locomotor mimicry in Heliconius butterflies: contrast analyses of flight morphology and kinematics
Mllerian mimicry is a mutualism involving the evolutionary convergence of colour patterns of prey on a warning signal to predators. Behavioural mimicry presumably adds complexity to the signal and ...

Shivering and its cost during reproductive behaviour in Neotropical owl butterflies, Caligo and Opsiphanes (Nymphalidae: Brassolinae)
Abstract Abstract. Male owl butterflies Caligo and Opsiphanes were gathered during crepuscular hours along an edge habitat, where they engaged either other males of the same species in aerialExpand

CORRELATIONS OF THE POSITION OF CENTER OF BODY MASS WITH BUTTERFLY ESCAPE TACTICS
Using the evolution of neotropical butterflies as a natural experiment, we examine Ellington9s biomechanical hypothesis that the position of center of body mass affects insect maneuverability. WeExpand
